- Create packages/highlight with shared Lezer-based syntax highlighting (types, parsers, highlighter, color maps) - Add syntax highlighting and line numbers to file-pane.tsx with memoized CodeLine component - Import shared highlight colors in git-diff-pane.tsx instead of local definitions - Delete duplicated syntax-highlighter.ts from both app and server - Fix TSX dialect to "ts jsx" (correct per Lezer docs)
