* General
- Fix the benchmark require wrapper function to work in Lua
- Fix memory leak in the new Luau C API test
* New Solver
- Luau: type functions should be able to signal whether or not irreducibility is due to an error
- Do not generate extra expansion constraint for uninvoked user-defined type functions
- Print in a user-defined type function should be reported as an error
instead of logging to stdout
- Many e-graphs bugfixes and performance improvements
- Many general bugfixes and improvements to the new solver as a whole
- Fixed issue with Luau used-defined type functions not having all environments initialized
- Infer types of globals under new type solver
* Fragment Autocomplete
- Miscellaneous fixes to make interop with the old solver better
* Runtime
- Support disabling specific Luau built-in functions from being
fast-called or constant-evaluated
- Added constant folding for vector arithmetic
- Added constant propagation and type inference for Vector3 globals

## What's Changed?
* Optimized the vector dot product by up to 24%
* Allow for x/y/z/X/Y/Z vector field access by registering a `vector` metatable
with an `__index` method
* Fixed a bug preventing consistent recovery from parse errors in table types.
* Optimized `k*n` and `k+n` when types are known
* Allow fragment autocomplete to handle cases like the automatic insertion of
parens, keywords, strings, etc., while maintaining a correct relative positioning
### New Solver
* Added support for 'thread' and 'buffer' primitive types in Luau user-defined
type functions
* Allow for `nil` assignment to tables and classes with indexers
