Numeric, ordering and equality traits (#2433)
* Adapts to https://github.com/anoma/juvix-stdlib/pull/86
* Adds a pass in `toEvalTransformations` to automatically inline all
record projection functions, regardless of the optimization level. This
is necessary to ensure that arithmetic operations and comparisons on
`Nat` or `Int` are always represented directly with the corresponding
built-in Core functions. This is generally highly desirable and required
for the Geb target.
* Adds the `inline: always` pragma which indicates that a function
should always be inlined during the mandatory inlining phase, regardless
of optimization level.

Add constructor wildcards (#2437)
- Closes #2402.

Changes:
1. Allow the definition of empty record types.
2. Introduce the _constructor wildcard_ pattern. That is, a pattern of
the form `constr@{}` that matches the constructor `constr` regardless of
its number of arguments.

Update Geb backend (#2436)
Changes in the printing of Lambda terms necessary for the use of the Juvix
Geb backend, changing the names of binary operations, adding a
constructor for natural numbers. Appropriately changes tests when
necessary.

Improve the specialisation optimisation (#2417)
* Closes #2416 
* Closes #2401 
* Avoids generating identical specialisations by keeping a
specialisation signature for each specialised function application.
* Allows to specialise on a per-trait or per-instance basis:
```
{-# specialize: true #-}
trait
type Natural N := mkNatural {
  + : N -> N -> N;
  * : N -> N -> N;
  fromNat : Nat -> N;
};
```
or
```
{-# specialize: true #-}
instance
naturalNatI : Natural Nat := ...
```
* The above `specialize: bool` pragma actually works with any type or
function. To be able to simultaneously specify the boolean
specialisation flag and specialisation arguments, one can use
`specialize-args: [arg1, .., argn]` which works like `specialize: [arg1,
.., argn]`.

Add juvix dependencies update command (#2419)
This PR adds a new command `juvix dependencies update` that fetches all
dependencies in a project and updates the project lock file.

Currently the only way to update the lock file is to delete it and
generate a new one.

## CLI Docs

```
juvix dependencies --help
Usage: juvix dependencies COMMAND

  Subcommands related to dependencies

Available options:
  -h,--help                Show this help text

Available commands:
  update                   Fetch package dependencies and update the lock file
```

## Example

A project containing the following `juvix.yaml`

```yaml
dependencies:
  - .juvix-build/stdlib/
  - git:
      url: https://github.com/anoma/juvix-test
      ref: v0.6.0
      name: test
main: Example.juvix
name: example
version: 1.0.0
```

compile to generate the lockfile: `juvix compile`

```yaml
# This file was autogenerated by Juvix version 0.5.1.
# Do not edit this file manually.

dependencies:
- path: .juvix-build/stdlib/
  dependencies: []
- git:
    name: test
    ref: a94c61749678ff57556ee6e4cb1f8fbbddbc4ab1
    url: https://github.com/anoma/juvix-test
  dependencies:
  - git:
      name: stdlib
      ref: 4facf14d9b2d06b81ce1be1882aa9050f768cb45
      url: https://github.com/anoma/juvix-stdlib
    dependencies: []
```

Now update the test dependency version:

```yaml
- .juvix-build/stdlib/
- git:
   url: https://github.com/anoma/juvix-test
   ref: v0.6.1
   name: test
main: Example.juvix
name: example
version: 1.0.0
```

And run `juvix dependencies update`

Now the lockfile has updated to the hash of v0.6.1:

```yaml
# This file was autogenerated by Juvix version 0.5.1.
# Do not edit this file manually.

dependencies:
- path: .juvix-build/stdlib/
  dependencies: []
- git:
    name: test
    ref: a7ac74cac0db92e0b5e349f279d797c3788cdfdd
    url: https://github.com/anoma/juvix-test
  dependencies:
  - git:
      name: stdlib
      ref: 4facf14d9b2d06b81ce1be1882aa9050f768cb45
      url: https://github.com/anoma/juvix-stdlib
    dependencies: []
```

Add package lockfile support (#2388)
This PR adds lock file support to the compiler pipeline. The lock file
is generated whenever a compiler pipeline command (`juvix {compile,
typecheck, repl}`) is run.

The lock file contains all the information necessary to reproduce the
whole dependency source tree. In particular for git dependencies,
branch/tag references are resolved to git hash references.

## Lock file format

The lock file is a YAML `juvix.lock.yaml` file written by the compiler
alongside the package's `juvix.yaml` file.

```
LOCKFILE_SPEC: { dependencies: { DEPENDENCY_SPEC, dependencies: LOCKFILE_SPEC }
DEPENDENCY_SPEC: PATH_SPEC | GIT_SPEC
PATH_SPEC: { path: String }
GIT_SPEC: { git: {url: String, ref: String, name: String } }
```

## Example

Consider a project containing the following `juvix.yaml`:

```yaml
dependencies:
- .juvix-build/stdlib/
- git:
   url: https://github.com/anoma/juvix-containers
   ref: v0.7.1
   name: containers
name: example
version: 1.0.0
```

After running `juvix compile` the following lockfile `juvix.lock.yaml`
is generated.

```yaml
# This file was autogenerated by Juvix version 0.5.1.
# Do not edit this file manually.

dependencies:
- path: .juvix-build/stdlib/
  dependencies: []
- git:
    name: containers
    ref: 3debbc7f5776924eb9652731b3c1982a2ee0ff24
    url: https://github.com/anoma/juvix-containers
  dependencies:
  - git:
      name: stdlib
      ref: 4facf14d9b2d06b81ce1be1882aa9050f768cb45
      url: https://github.com/anoma/juvix-stdlib
    dependencies: []
  - git:
      name: test
      ref: a7ac74cac0db92e0b5e349f279d797c3788cdfdd
      url: https://github.com/anoma/juvix-test
    dependencies:
    - git:
        name: stdlib
        ref: 4facf14d9b2d06b81ce1be1882aa9050f768cb45
        url: https://github.com/anoma/juvix-stdlib
      dependencies: []
```

For subsequent runs of the juvix compile pipeline, the lock file
dependency information is used.

 ## Behaviour when package file and lock file are out of sync

If a dependency is specified in `juvix.yaml` that is not present in the
lock file, an error is raised.

Continuing the example above, say we add an additional dependency:

```
dependencies:
- .juvix-build/stdlib/
- git:
     url: https://github.com/anoma/juvix-containers
     ref: v0.7.1
     name: containers
- git:
     url: https://github.com/anoma/juvix-test
     ref: v0.6.1
     name: test
name: example
version: 1.0.0
```

`juvix compile` will throw an error:

```
/Users/paul/tmp/lockfile/dep/juvix.yaml:1:1: error:
The dependency test is declared in the package's juvix.yaml but is not declared in the lockfile: /Users/paul/tmp/lockfile/dep/juvix.lock.json
Try removing /Users/paul/tmp/lockfile/dep/juvix.lock.yaml and then run Juvix again.
```

Add Partial trait (#2409)
Adds a Partial trait to the standard library, similar to the one in
PureScript:

https://book.purescript.org/chapter6.html#nullary-type-classes

This enables using partial functions in an encapsulated manner and
without depending on the Debug module.

Adds a trait:

```
trait
type Partial := mkPartial {
   fail : {A : Type} -> String -> A
};

runPartial {A} (f : {{Partial}} -> A) : A := f {{mkPartial Debug.failwith}};

Record creation syntax with function definitions (#2369)
* Closes #2280 
* Record creation syntax uses normal function definition syntax like at

* It is now allowed to omit the result type annotation in function
definitions (the `: ResultType` part) with `_` inserted by default. This
is allowed only for simple definitions of the form `x := value` in lets
and record creation, but not at the top level.

Add nodes with no edges to the dependency graph (#2390)
- Closes #2373 

Consider this:
```
let 
 x : _ := 0
in ...
```
When translating the let to internal, we build the dependency graph and
then use that to group definitions in mutually recursive blocks. Since
`x` has no edge, it was not being added to the dependency graph, so it
was not being translated to Internal, thus crashing later during
inference.

Avoid serialization of _packageFile field in juvix.yaml (#2381)
The _packageFile field of the Package record is used internally to track
the package file path and is used in error messages. It is not intended
to be present in the juvix.yaml file.

To express this the PackageFileType family with the Raw index is set to
`()`. However `()` is serialized to an empty array by Aeson, so the
`file: []` field was added to juvix.yaml.

NB: From aeson 2.2, fields with type `()` are ommitted when the
`omitNothingFields` flag is set to True, as it is for the package ToJSON
instance.

The solution in this PR is to set `PackageFileType 'Raw` to `Maybe ()`.
The
`omitNothingFields` flag then omits this field from the serialized
package object.

Do not call git fetch on git dependency if ref already exists in clone (#2379)
During path resolution, `git fetch` is called on every git dependency
clone. It's desirable to reduce the number of `git fetch` calls because
it makes a network call.

This PR changes the git dependency resolution to only call `git fetch`
if the existing clone does not already contain the specified ref.

Avoid the -Os option when generating WebAssembly (#2378)
With `-Os` ill-typed code is generated for the following:
```
module wasmcrash.juvix;

import Stdlib.Prelude open;

{-# inline: false #-}
I {A} (x : A) : A := x;

{-# inline: false #-}
I' {A} (x : A) : A := x;

main : Nat := I' (I I 1);
```
Running the generated WASM file with `wasmer` or `wasmtime` gives an
error:
```
Validation error: type mismatch: expected i32 but nothing on stack (at offset 740)
```
The issue occurs with clang version 16.0.5 but not 16.0.0. The issue
does not occur with any other optimization option (`-O1`, `-O2`, `-O3`).
There is no issue with `-Os` used with the native target.

This is thus likely a bug in a specific version of LLVM. It could be
theoretically some very subtle non-conformance to the C standard in our
generated code, but this seems less likely. Creating a minimum C file
exposing the bug would be very time-consuming, so I propose to just
avoid using the `-Os` option for now.

New fixity/iterator syntax (#2332)
- Closes #2330
- Closes #2329 

This pr implements the syntax changes described in #2330. It drops
support for the old yaml-based syntax.
Some valid examples:
```
syntax iterator for {init := 1; range := 1};

syntax fixity cons := binary {assoc := right};
syntax fixity cmp := binary;
syntax fixity cmp := binary {}; -- debatable whether we want to accept empty {} or not. I think we should
```
# Future work
This pr creates an asymmetry between iterators and operators
definitions. Iterators definition do not require a constructor. We could
add it to make it homogeneous, but it looks a bit redundant:
```
syntax iterator for := mkIterator {init := 1; range := 1};
```

We could consider merging iterator and fixity declarations with this
alternative syntax.
```
syntax XXX for := iterator {init := 1; range := 1};

syntax XXX cons := binary {assoc := right};
```
where `XXX` is a common keyword. Suggestion by @lukaszcz XXX = declare
