JS plugins and parser fixes land

Biome adds AST-querying JS plugins, fixes incomplete Svelte/JS parsing, and patches workspace cache eviction.

JS plugins can now query AST nodes by kind (siketyan7dbf9d8)

Biome’s JS plugin API now exposes a way to ask for AST nodes by syntax kind, and the plugin runtime/codegen were expanded to support it. This reduces plugin dispatch overhead and gives plugin authors a more direct, type-safe way to target node shapes.

Biome no longer crashes on incomplete Svelte declarations (dyc3a51eff7)

Parsing incomplete let/const declarations inside Svelte files now falls back more gracefully instead of crashing. The fix adds new bogus declaration handling and updates formatter/parser snapshots so malformed input is recovered consistently.

Workspace DB eviction now clears parsed file cache (ematipico405dedb)

The LSP workspace database now evicts cached parsed sources when files or whole paths are unloaded, fixing a memory leak over long editor sessions. Tests were added to verify that cache eviction actually shrinks the stored source set.

Other misc changes

  • Split the just test-lintrule helper into per-language commands.
  • Added more CSS rule sources for biome migrate eslint.
