Merge branch 'main' into claude/fix-bun-main-bytecode-cache

The bun:main hardcoded module path was not attaching bytecode from the
standalone module graph, causing a bytecode cache miss for the entry point
in --compile --bytecode builds.

Now when loading bun:main in a standalone executable, the entry point's
bytecode, bytecode_origin_path, and module_info are looked up from the
standalone module graph and attached to the ResolvedSource.
