## Description
Making the schema work for boolean expressions has been challenging as
they are no longer tied to a single data connector, so we cannot do any
checks of whether a relationships is local or remote. We defer this to
the IR step when the source data connector for a relationship is known,
so that we can generate schema for boolean expressions decoupled from
any concept of data connector.
Functional no-op.

## Description
This PR moves all the tests that were added to
`crates/engine/tests/validate_metadata_artifacts/aggregate_expressions`
to the metadata-resolve `metadata_golden_tests`.
All the `error.txt` files got renamed to `expected_error.txt` and the
`metadata is not consistent:` bit on the front of the error got trimmed
off.
I had to change the way that `test_failing_metadata` works so that
instead of looking for directories under `failing/` it looks for
`metadata.json` files under `failing/`. This is because not every
directory has a test in it, some directories are just used for grouping
(eg `failing/aggregate_expressions/`). This doesn't change what tests
get run. The only side effect is that every test name has `_metadata`
suffixed to it (the filename). 😢 `test-each` doesn't appear to offer a
way to disable this behaviour.

## Description
This PR implements the GraphQL API for aggregate root fields. The
GraphQL schema matches the design in the [Aggregate and Grouping
RFC](https://github.com/hasura/v3-engine/blob/main/rfcs/aggregations.md#aggregations-walkthrough).
### Schema Generation
The main new part of the GraphQL schema generation can be found in
`crates/schema/src/aggregates.rs`. This is where we generate the new
aggregate selection types. However, the root field generation can be
found in `crates/schema/src/query_root/select_aggregate.rs`.
The new `filter_input` type generation lives in
`crates/schema/src/model_filter_input.rs`. As this type effectively
encapsulates the existing field arguments used on the Select Many root
field, the code to generate them has moved into `model_filter_input.rs`
and `select_many.rs` simply reuses the functionality from there (without
actually using the filter input type!).
### IR
The main aggregates IR generation for the aggregate root field happens
in `crates/execute/src/ir/query_root/select_aggregate.rs`. It reads all
the input arguments to the root field and then kicks the selection logic
over to `model_aggregate_selection_ir` from
`crates/execute/src/ir/model_selection.rs`.
`crates/execute/src/ir/model_selection.rs` has received some refactoring
to facilitate that new `model_aggregate_selection_ir` function; it
mostly shares functionality with the existing `model_selection_ir`,
except instead of creating fields IR, it creates aggregates IR instead.
The actual reading of the aggregate selection happens in
`crates/execute/src/ir/aggregates.rs`.
The aggregates selection IR captures the nested JSON structure of the
aggregate selection, because NDC does not return aggregates in the same
nested JSON structure as the GraphQL request. NDC takes a flat list of
aggregate operations to run. This captured nested JSON structure is used
during response rewriting to convert NDC's flat list into the nested
structure that matches the GraphQL request.
The aggregate selection IR is placed onto `ModelSelection` alongside the
existing fields IR. Since both fields and aggregates can be put into the
one NDC request (even though they are not right now), this made sense.
They both translate onto one NDC `Query`. This necessitated making the
field selection optional on the `ModelSelection`
(`ModelSelection.selection`), since aggregate requests currently don't
use them.
### Planning
`crates/execute/src/plan/model_selection.rs` takes care of mapping the
aggregates into the NDC request from the generated IR.
There has been a new `ProcessResponseAs` variant added in
`crates/execute/src/plan.rs` to capture how to read and reshape an NDC
aggregates response. This is handled in
`crates/execute/src/process_response.rs` where the captured JSON
structure in the IR is used to restore NDC's flat aggregates list into
the required nested JSON output structure.
### Testing
The Custom Connector has been updated with functionality to allow
aggregates over nested object fields
(`crates/custom-connector/src/query.rs`).
New execution and introspection tests have been added to
`crates/engine/tests/execute/aggregates/` to test aggregates against
Postgres and the Custom Connector.

## Description
This PR implements the metadata resolve phase of the engine and adds
support for resolving `AggregateExpression`s and validates their use
when linked to a `Model`.
The bulk of the changes can be found in:
* `crates/metadata-resolve/src/stages/aggregates/*` - This is where the
`AggregateExpression`s are resolved
* `crates/metadata-resolve/src/stages/models/mod.rs` - This is where we
validate the `AggregateExpression` specified for use in the model is
actually compatible with the model and its data connector
The `ndc-spec` version used has been lifted to the latest version that
adds support for aggregates over nested objects
(https://github.com/hasura/ndc-spec/pull/144). This necessitated changes
in the Custom Connector, but actual functionality to implement
aggregation over nested objects is implemented in Part 3.
There are also some changes in
`crates/metadata-resolve/src/types/subgraph.rs` where the `Display`
trait for the various `Qualified<T>`, `QualifiedTypeReference`, etc
types has been reworked so that they print more cleanly, with the
subgraph being put outside the type syntax, and array types getting
formatted correctly. For example, previous an array of Varchars would
have printed as `Varchar (in subgraph default)!`, now it properly
formats as `[Varchar!]! (in subgraph default)`.
This was necessary to make useful error messages using these types.
A tonne of tests have been added in
`crates/engine/tests/validate_metadata_artifacts/aggregate_expressions`
to test every error condition of the metadata resolve process.

## 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.

It turns out that code generators based on JSON schemas don't always
play nicely with characters such as `' '` or `'/'`. To work around this,
when we use the schema name as a title, we replace any non-alphanumeric
character or underscore with an underscore (`'_'`).

## Description
This adds the ability to describe nested object boolean expressions,
which become `fieldPath` items in the generated
`ndc_models::ComparisonTarget::Column` items. This allows us to describe
filtering a `User` based on some element in their nested `address` field
(like `postcode`, for example).
Like the other `BooleanExpressionType` work, this remains behind a
feature flag so should make no user-facing changes.
It is also missing a whole heap of metadata resolve checks, going to
follow with these after doing the happy path to unblock other work.

## Description
When we generate a JSON schema via `schemars`, we end up with duplicate
types in the schema, which get names like `ValueExpression2`, `Role2`,
and so on. This isn't ideal, and seems to arise for two reasons:
1. The type is polymorphic, and is monomorphised in two ways, and thus
the types can't be unified.
2. The type is monomorphic, but is used inside and outside of its home
module.
The first problem was fixed previously by splitting polymorphic types,
but the second has proven to be a bit more work. This PR finally solves
the problem by introducing a new library, `jsonschema-tidying`:
* First, we search the definitions within the JSON schema for any whose
names end in a number, such as `ValueExpression2` or `MetadataV2`.
* Then, we look for types whose names match everything up to the final
numeric digits, and discard any types for whom we can't find a match (so
we keep `ValueExpression2` because `ValueExpression` exists, but discard
`MetadataV2` because `MetadataV` does not).
* Next, we remove the duplicate definition from the definitions map,
potentially breaking links in both the schema _and_ the rest of the
definitions map.
* Finally, we traverse the entirety of the tree looking for any
references to the duplicate entry, and replace them with references to
the original entry.
This PR has no direct user-facing change, however it _will_ have an
effect on the docs generation code, which will hopefully result in
tidier documentation.

## 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.
