Add automated grammar build pipeline and improve CI/CD
Add grammar-sources.json as the single source of truth mapping each language to its tree-sitter repository and subdirectory path. Add build-grammars.ts script that clones, generates, and compiles parser.wasm files for all or specific languages. Add build-grammars GitHub Actions workflow that triggers on extension changes, builds missing wasm files, and deploys them to CDN via rsync. Improve deploy workflow to use direct rsync instead of SSH shell commands, and add grammar-sources.json validation to the validate workflow. This replaces the manual SSH-and-build approach with a fully automated pipeline that OSS contributors can trigger via PR.
