* feat(files): edit workspace files on web
Keep source buffers synchronized with host file changes and require an explicit overwrite or reload when revisions diverge.
* feat(panels): surface and protect modified tabs
Expose tooltip and modification state through the generic panel boundary so tabs can show stable metadata and guard every close route consistently.
* fix(tests): use portable fake timeout handle
* fix(files): harden editor conflict handling
Preserve modified panel state across tab eviction, use precise revisions for optimistic writes, coalesce concurrent file watchers, and localize the editor interface.
* fix(files): close editor concurrency gaps
Coalesce clean reloads, preserve subscriber identities and file permissions, suspend pending saves during close confirmation, and carry precise revisions through file reads.
* test(files): expect read revision metadata
Wire the @replit/codemirror-lang-csharp Lezer grammar into @getpaseo/highlight following the existing per-language pattern (Java/Rust/Swift). Map the cs extension to the parser and alias the csharp and c# markdown fence names so fenced code blocks highlight.
Register csharpLanguage.parser rather than the package's raw parser export: the highlight styleTags are applied only inside csharpLanguage (via parser.configure), so the raw parser would parse but render unstyled.

Keep parsed chat and tool detail content in sync with appearance token changes. Hide font-family controls on native, use One as the default syntax theme, add Swift highlighting, and give Nord a distinct light palette.
- 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)
