### What
This PR fixes a bug with variable nullability coercion. Specifically,
providing a non-null variable for a nullable field should work, as all
non-nullable variables can be used as nullable variables via "coercion".
Related issues:
* https://hasurahq.atlassian.net/browse/V3ENGINE-243
* https://github.com/hasura/v3-e2e-testing/pull/224 (the test for this
change)
### How
I think someone did something clever with macros, so I tried to unpack
the macro to make sense of it, and in the process, spotted the bug: it's
not that both the location must be nullable AND the variable not, it's
that _if_ the variable is nullable, the location must not be nullable.

### What
The `lazy_static` macro is poorly maintained, fairly bloated, and has
been mostly superseded by
[`OnceLock`](https://doc.rust-lang.org/stable/std/sync/struct.OnceLock.html)
in the stdlib.
### How
1. I turned a couple of `static ref` values into `const`, sometimes by
creating `const fn` equivalents to other functions.
2. I inlined static behavior to construct a JSON pointer into some
tests, where we don't care too much about losing a few milliseconds.
3. For the rest, I replaced `lazy_static` with a `static OnceLock` and a
call to `OnceLock::get_or_init`.

## Description
According to NDC headers pass-through spec, commands can include headers
in their responses, which are forwarded as response headers by the
engine to the client. This PR implements it.

I noticed a few extra calls to `.clone()` while working on an unrelated
refactor. I want to remove them for brevity and simplicity; I don't
expect a performance improvement.
This turns on the Clippy warning `redundant_clone`, which detects
unnecessary calls to `.clone()` (and `.to_string()`).
It is an unstable warning and so might reports some false positives. If
we find any, we can suppress the warning there.

## Description
A few debug lines slipped in recently, let's make `clippy` `warn` on
those, so they are kicked out by CI. Functional no-op.
V3_GIT_ORIGIN_REV_ID: 290f6de35f9315b68811eb5f15969fb0333e9d06
This keeps versions in one place so we can more easily ensure we upgrade
crates together.
V3_GIT_ORIGIN_REV_ID: 6a929bb6196c19a1f66a768585b669127035e9be
Return a `T` instead of a `Result<T, E>` when we never return an error
(`E`) case.
I also enabled some more warnings. `unnecessary_box_returns` has been
suppressed where appropriate, and `unused_async` doesn't seem to be
violated anywhere any more.
I got rid of some calls to `.unwrap()` too.
V3_GIT_ORIGIN_REV_ID: 015ebd05978cf8c2d87474a90e0cd4333779a761
We pretend we handle directives but we simply set them to an empty map,
and then don't actually use them at all.
This is completely unused code that can be removed.

## Description
It turns out that every usage of `Builder::allow_all_namespaced`
concerned itself with either introspection nodes or (in the GDS case)
`None`.
Combined with the fact that both the SDL and GDS implementations of
`SchemaContext::introspection_namespace_node` were trivial, the
`NamespacedNodeInfo` contained in
`Namespaced::AllowAll(S::NamespacedNodeInfo)` is always functionally
meaningless.
This PR removes the `NamespacedNodeInfo` from `Namespaced::AllowAll` as
well as `SchemaContext::introspection_namespace_node`, thus simplifying
the implementation.

I also moved `implicit_hasher` and `return_self_not_must_use` to the
"definitely keep disabling this" list, and installed
[Bacon](https://dystroy.org/bacon/) in the Nix shell to make it easier

## Description
With the introduction of `NamespacedGetter` as the means deciding how to
interpret what it means to extract "namespaced" data from a schema it is
superfluous to thread along the "namespace" that lookups will be based
on.
This PR removes those namespace arguments.
As a nice side effect this removes the cases where we used to have to
supply a dummy role value when generating a role-agnostic schema.

1. Use `map_or(…, …)` instead of `.map(…).unwrap_or(…)`.
2. Use `.is_some_and(…)` instead of `.map(…).unwrap_or_default(…)`.
3. Nest `|` patterns where possible.
4. Be more specific about match patterns.
I found I could also simplify `typecheck_qualified_type_reference`
considerably.
V3_GIT_ORIGIN_REV_ID: 6a3b1a4c525c0187c2fdb6df0c979ca0b7b3016c
This PR refactors the schema crate to enable overriding the
interpretation of roles at runtime.
By providing a `NamespacedGetter` that ignores roles entirely (i.e.
`GDSNamespacedGetterAgnostic`) to schema generation functions it is
possible to derive a GraphQL schema that ignores permissions and
presets.
This PR leaves back a few opportunities to improve code clarity, which I
hope to address in follow-up PRs.
For instance, it seems superfluous to make sense for generic code
parametrised `<S: SchemaContext>` to carry around both a `S::Namespace`
and a `S::NamespaceGetter`, when all that code could ever do with that
`S::Namespace` value anyway is apply it to the `S::NamespaceGetter`.
Taking this line of reasoning to its conclusion suggests that we can
reduce the complexity of `trait SchemaContext` and its associated types
and kit.

Rather than allowing the `cast_precision_loss` and `inline_always`
warnings everywhere, we just suppress them in the few places they're
already used.
V3_GIT_ORIGIN_REV_ID: c28350a21efa029c8c6aae2a602eec2d75f42216
Add the ability to render field input-arguments and default values in
sdl.
Also add a small CLI tool to help inspect the GraphQL schemas that
result from a piece of engine metadata.

Just because it's fewer lines of code.
1. Invert `if`/`else` blocks with negative conditions.
2. Unwrap redundant `else` blocks.
3. Simplify a few branches to `let … else`.
4. Replace a `match` with `if let`.
V3_GIT_ORIGIN_REV_ID: 4f10730b688d21c1fc86a45ee5fb4adf008b3d94
Fix some warnings flagged by Clippy.
1. Elide `.into_iter()` where it's unnecessary.
2. Favor `&` over `.iter()`.
3. Use `.values()` on maps instead of discarding keys by destructuring.
4. Avoid `::from_iter(…)` in favor of `.collect()`.
I also replaced a call to `.cloned()` with `.copied()`.

`axum::Json` can work with any serializable type. Constructing a
`serde_json::Value` using `json!` just adds an intermediate step,
slowing down the conversion from structured data to the response bytes.
V3_GIT_ORIGIN_REV_ID: 8ae6352cb9a576988df5bf417e78d64706c7eb6e
The massive `Error` enum from `execute.rs` disintegrates into the
following independent error types.
- `RequestError`: All exceptions occurred before executing the root
field plans. Each variant in this error enum contains the error type
stemming from isolated steps in the pipeline involving parsing,
validation, IR conversion, and plan generation.
- `FieldError`: Exception occurred when resolving a field through its
plan. Multiple root fields are executed isolated, and field errors are
collected in a list.
Code paths for `explain` and `execute` query are split into two
functions. This is done to avoid few error variants and unburden the
function that previously does both.

## Description
1. I've moved the architecture information we had in `CONTRIBUTING.md`
to a separate document `docs/architecture.md` so we can evolve both
separately in the future.
2. I've introduced a couple of sub directories: `utils` and `auth`, for
supporting crates that are not the core functionality of the engine so
it is easier to find the most relevant crates.
New structure:
```
crates
├── auth
│ ├── dev-auth-webhook
│ ├── hasura-authn-core
│ ├── hasura-authn-jwt
│ └── hasura-authn-webhook
├── custom-connector
├── engine
├── lang-graphql
├── metadata-schema-generator
├── open-dds
└── utils
├── opendds-derive
├── recursion_limit_macro
└── tracing-util
```

I found myself wanting to rewrite JSON files with `sed`. The problem is,
then I want to run a formatter over them afterwards, and this will
change the whole file, not just the area I touched.
I would like to propose the nuclear option in remedying this: format
everything now. This is a very large change that should make it easier
to keep files to a consistent format in the future.
I have chosen to use Prettier for this because (a) it has a useful
`--write` command and (b) it also does GraphQL, Markdown, YAML, etc.
I've elected to exclude two sets of files:
1. `crates/custom-connector/data/*.json`, because they are actually
multiple JSON objects, one per line, which Prettier cannot parse.
2. `crates/lang-graphql/tests/**/*.graphql`, because it contains invalid
GraphQL, and the parser is intended to work with strangely-formatted
GraphQL.
The main changes are standardizing whitespace, adding a newline at the
end of files, and putting JSON arrays on one line when they fit.

arguments. It adds a `BooleanExpression` arm to `ValueExpression`, and
allows them to be resolved in the context of an ObjectType rather than
an entire model.
This means that if a boolean expression is passed to a command argument
that uses a field that doesn't exist, this happens:

The output of this PR is that we can resolve metadata for boolean
expressions in command arguments, and generate a GraphQL schema for
them, but will throw an error if one is actually used. This will be
resolved in the follow-up PR.

## Description
Previously boolean expressions were only used on where clauses for
models. We'd also like to use them for arguments for commands to make
permissions work. This PR splits a boolean expression from it's model.
This has the nice side effect of allowing the same boolean expression
type to used across multiple models, which is a sensible thing to want
to be able to do.
Before this change, using the same boolean expression type on two models
would give you this error:

This ensures only Criterion benchmarks get called by `cargo bench`.
Previously, some tests were being loaded too. This is an issue because
if we want to provide command-line arguments to Criterion, it will fail
if we run a non-Criterion benchmark.
We need to specify `harness = false` for each benchmark so that they
don't get wrapped by Cargo, and `bench = false` for everything that
doesn't contain benchmarks but _could_ (i.e. unit and integration
tests). I find Cargo very strange in this regard.
In addition, I fixed the validation benchmark by providing a valid SDL
schema.

## Description
This PR fixes the bug where passing a null value to a nullable input
field resulted in an error. It also uncomments the test for that.
JIRA: https://hasurahq.atlassian.net/browse/V3ENGINE-97
According to [the graphql
spec](https://spec.graphql.org/October2021/#sec-Null-Value):
>
>
> ```graphql
> {
> field(arg: null)
> field
> }
> ```
> The first has explicitly provided null to the argument “arg”, while
the second has implicitly not provided a value to the argument “arg”.
These two forms may be interpreted differently.
We are also considering the two cases separately, i.e., if something is
absent and nullable vs if something is set to null and is nullable. We
are not manually adding the nullable fields and setting them to null if
not specified explicitly.

When trying to reduce the number of dependencies we use in the engine, I
was blocked by a few `.clone()` calls that, on inspection, turned out to
be completely unnecessary.
I have replaced those with passing by reference, and then gone on a
pedant spree. I enabled the `needless_pass_by_value` Clippy warning and
fixed it everywhere that it highlighted. In most places, this meant
adding `&`, but I also marked some types as `Copy`, which makes
pass-by-value the right move.
In one place, I replaced calls to `async_map` with `if` and `else`, to
avoid constructing closures that capture across async boundaries. This
means I could just delete `async_map`.

Previously, negative values for `offset` and `limit` input fields
resulted in an internal error and not exposed in the API response. The
reason is that these errors are raised from normalized_ast conversion
after GraphQL validation. The validation will only check for the type,
but not the value of the input fields.
This Commit:
- Introduces a utility function to lift any unexpected value internal
error to external.
- Use the function for `limit` and `offset` input field value coercion.

## Description
In https://github.com/hasura/v3-engine/pull/441 we made all our skipped
Clippy rules explicit. This enables one (pretty arbitrarily) and fixes
what comes up.

## Description
Following the approach taken here:
https://github.com/hasura/ndc-postgres/pull/402
This moves the `clippy` settings into the Cargo workspace file instead
of passing them for each invocation.
We enable all pedantic settings, run `cargo clippy --fix` to auto fix a
few things, and then manually disable all other lints.
Plenty of them are worth enabling and fixing in future IMO.
