Syntax Highlighting — Rebuilt from the Ground Up

Every tree-sitter parser (all 35 languages) has been rebuilt from source using the latest tree-sitter-cli, resolving a long-standing WASM ABI version mismatch that silently broke syntax highlighting across most languages. Highlighting for YAML, JSX/TSX, and SQL now works correctly, and all grammars use the modern dylink.0 format expected by the runtime.

New: SQL Syntax Highlighting

SQL files are now fully supported with syntax highlighting powered by a dedicated tree-sitter grammar — previously, SQL had no highlighting at all.

Editor Polish

• The inline edit model selector now uses a cleaner sparkle icon
• GitHub PRs panel layout has been tightened for better readability

Under the Hood

• Removed the pre-built tree-sitter-wasms package entirely — all 35 parsers are now compiled from individual grammar sources during setup
• Switched YAML, Markdown, and Vue grammars to the @tree-sitter-grammars maintained forks (C-compatible scanners for reliable WASM builds)
• Updated YAML highlights query to match the new grammar structure
