Why

Runtime 15.0.0 packs primary query states into bits and narrows shared lexer-mode IDs. This rebuild adopts that representation and the runtime's cached query-state membership. The Wasm payload is 242,851 bytes versus 247,523 bytes in published 12.0.1 (4,672 bytes smaller).

Requirements

• required: Improve both performance and binary size in tree-sitter and our grammar repositories as much as possible, ignoring backward compatibility.
• required: Keeping the current tree structure is not necessary.
• required: For each PR, run review-booster, complete-pr, and release in that order.
• chosen: Adopt runtime/generator 15.0.0 in this repository to ship the shared compact metadata with its matching ABI.
• chosen: Keep the existing generation profile and compiler optimization settings to isolate metadata packing from compiler tuning.
• chosen: Keep language rules and query sources unchanged while rebuilding their generated artifacts.

Customer Summary

Ships compact parser metadata and requires the matching WillBooster runtime 15.x. Upgrade the grammar and runtime together.

Technical Summary

Pin the Web and Rust runtimes to 15.0.0, update the optional Web peer range, and regenerate the parsers and headers with the official CLI for that release. Language ABI is 0x5742000b.

Testing

bun run build-wasm and bun run verify pass. bun wb test passes for test/unit/corpus.test.ts, test/unit/wasm.test.ts, test/unit/incremental.test.ts, test/unit/modifierQueries.test.ts, test/unit/moduleProviders.test.ts. The full suite, platform matrix, and publication checks run in PR CI.
