What's Changed

• Fragment Autocomplete: a new API allows for type checking a small fragment of code against an existing file, significantly speeding up autocomplete performance in large files.
• Requiring a path with a ".lua" or ".luau" extension will now have a bespoke error suggesting to remove said extension.
• Fixes a bug in which whether two Luau::Symbols are equal depends on whether the new solver is enabled.
• Fix definition module name & location by @checkraisefold in #1495
• Pre-populate/duplicate check class definitions (new solver) by @checkraisefold in #1493
• Set the defining module even when the new solver cloned the type. by @aatxe in #1506
• Replace old site urls by @Barocena in #1505

New Solver

• E-Graphs have landed: this is an ongoing approach to make the new type solver simplify types in a more consistent and principled manner, based on similar work (see: https://egraphs-good.github.io/).
• Adds support for exporting / local user type functions (previously they were always exported).
• Fixes a set of bugs in which the new solver will fail to complete inference for simple expressions with just literals and operators.
