* feat: search-based code navigation with peek view (#694)
Add IDE-like code navigation to the review UI. Cmd/Ctrl+click a token
in a diff to find its definitions and references across the repo via
ripgrep, displayed in a VS Code-style peek panel below the diff.
Backend: bounded rg search with language-aware definition patterns
(TS/JS, Python, Go, Rust), ranked results (same file > changed files >
same directory), confidence labels, and graceful degradation when rg
is not installed. Both Bun and Pi servers implement the endpoints.
Frontend: Dockview peek panel with syntax-highlighted full-file preview
on the left and grouped reference list on the right. Clicking a
reference scrolls the preview; double-clicking an in-diff result
navigates to the file with a gold line flash.
Closes#694
* fix: resolve Pi server TypeScript errors for code-nav
Add missing spawn import, type the close callback parameter,
and use double-cast for parseBody → CodeNavRequest.
* fix: clear loading state on cached preview hits
Without this, clicking a cached file while a fetch is in-flight
leaves isLoading stuck true — the spinner hides the preview.
* feat: show pointer cursor on Cmd/Ctrl+hover for navigable tokens
Adds pn-token-nav class with thicker underline and pointer cursor
when hovering a token while holding the modifier key, signaling
the token is Cmd+clickable for code navigation.
* refactor: remove go-to-diff navigation from peek panel
Strip the in-diff badge, double-click-to-jump, highlightDiffLine
wiring, and onCodeNavGoToDiff from the peek panel. The peek view
is the primary interaction — jump-to-diff adds complexity without
clear value at this stage.
* chore: remove dead code from code-nav cleanup
Delete unused highlightDiffLine.ts, remove codeNavChangedFiles
and codeNavActiveSide from context and App.tsx, drop stale
extractChangedFiles import.
* chore: add code-nav endpoints to AGENTS.md, remove dead activeSide state
* fix: don't classify bare indented calls as definitions
Change the TS/JS method pattern from zero-or-more (*) to
one-or-more (+) declaration keywords, so plain calls like
startServer(config) are no longer misclassified as definitions.
* feat: show toast when code-nav is unavailable in platform-only PR mode
Instead of opening the peek panel and showing misleading "No results",
Cmd+click in non-local PR mode shows a brief toast explaining that
code navigation requires a local checkout.
* fix: strip hljs hardcoded background from code-nav preview
The highlight.js github-dark theme sets a fixed dark background
on all .hljs elements. Apply transparent override for the entire
peek preview so code inherits the active theme's background.
