Revise GHA workflows for prototyping () 
Changed the GHA workflows to:
- Not run `build` and `release` workflows for PRs that only affect `prototyping/`
- Run `prototyping` workflow when PRs affect `Analysis/**`, `Ast/**`, or the `luau-ast` source files

Emit more information for AstLocals in JSON encoder () 
We don't emit type annotations right now for `AstLocal`s in the JSON encoder. This makes it really hard to surface annotations in the Agda implementation. This PR changes it to emit location and type annotations, if present.

Update library.md () 
Clarify the relationship between `typeof` and `newproxy`. As a sandboxing measure, `typeof` only uses `__type` on host-defined userdata.

Fixes .

Add Luau.Ast.CLI target () 
Adds a `luau-ast` CLI that dumps Luau source to JSON. @asajeffrey and I are planning to use this functionality to construct an Agda model of the Luau type system/operational semantics, to allow formally proving properties of Luau's type systems.

- Improve refinement support for unions, in particular it's now possible to implement tagged unions as a union of tables where individual branches use a string literal type for one of the fields.
- Fix `string.split` type information
- Optimize `select(_, ...)` to run in constant time (~2.7x faster on VariadicSelect benchmark)
- Improve debug line information for multi-line assignments
- Improve compilation of table literals when table keys are constant expressions/variables
- Use forward GC barrier for `setmetatable` which slightly accelerates GC progress

- TableOperations lint now includes a warning for table.create(N, {}) (which is likely a mistake since the table is shared by all entries)
- Type checker now type checks #v when v is a union
- Parser now rejects sources that consists of a single unfinished long comment
- Work around significant MSVC 2022 performance regression, bringing it more or less in line with MSVC 2019
- Compiler now predicts array size for newly allocated tables when the table is filled in a short loop
- Small improvements in compilation throughput (~2% faster)
- Implement paged sweeper for GC which improves sweep throughput 2-3x and reduces memory consumption by 8 bytes per object (once it is stabilized we will see additional 8 bytes per object of savings)
- Improve Repl Tab completion
- Repl now supports -i (interactive mode to run code in context of a script's environment) and -On (to control optimization flags)

- Rework transaction log used for type checking which should result in more robust type checking internals with fewer bugs
- Reduce the amount of memory consumed by type checker on large module graphs
- Type checker now errors on attempts to change the type of imported module fields
- The return type of newproxy is now any (fixes )
- Implement new number printing algorithm (Schubfach) which makes tostring() produce precise (round-trippable) and short decimal output up to 10x faster
- Fix lua_Debug::linedefined to point to the line with the function definition instead of the first statement (fixes )
- Fix minor bugs in Tab completion in Repl
- Repl now saves/restores command history in ~/.luau_history

This version isn't for release because we've skipped some internal
numbers due to year-end schedule changes, but it's better to merge
separately.
