feat: show file change summary bar (#950)

* feat: add FileChangeSummary component for multi-file diff preview in ToolPart Provides an aggregated diff card for apply_patch and multi-edit tools, showing per-file stats with click-to-expand diff view. * feat: add PendingChangesBar above chat input with collapse/expand and file opening - Collapsed/expanded toggle with aggregate +N -N stats (green/red) - Relative path display, chat-column alignment with ChatInput - Click file to open in diff viewer (web/desktop) or editor (VS Code) - Support edit/multiedit/apply_patch/write tool metadata extraction - Add PendingChangesBar to main chat view (ChatContainer) * feat: dual-mode ChangedFilesBar — Git diff state vs latest AI turn Git mode: reads git status from useGitStore (status.files + diffStats), auto-clears on commit/restore. Shows 'N files changed in workspace'. Non-Git mode: latest assistant turn only (no accumulation), clears on new user message or manual dismiss. Shows 'AI updated N files in the last reply'. Both modes: dismiss button with signature-based tracking. Add pendingChangesBarDismissed state to session-ui-store, cleared on sendMessage. * fix: address code review issues in ChangedFilesBar - Gate non-git mode on streaming state to prevent flicker during AI turns - Return null when isGitRepo is unknown (loading state) - Add group/row class for reject button visibility in FileChangeSummary - Use per-session Map for dismiss tracking to prevent cross-session leaks - Include additions/deletions in dismiss signature for re-edit detection - Extract shared parsePatchStats/parseCount to fileChangeHelpers * chore: revert local .opencode/package-lock.json changes from PR * fix: per-part fallback guard and git-only reject button - Fix extractChangedFiles to use per-part files.length snapshot instead of global guard, preventing file entries from being skipped when earlier parts already contributed files - Hide reject button in FileChangeSummary when not in a git repo, preventing silent revert failures * refactor: remove FileChangeSummary — dead code redundant with ToolPart FileChangeSummary duplicated diff rendering that ToolPart already provides (PatchDiff, per-file stats, DiffViewToggle). The only unique feature was a git revert button, which conflicts with the design principle of not having accept/reject on file change previews. Moved parsePatchStats/parseCount back into PendingChangesBar (sole consumer) and deleted the shared helper module. * chore: remove stray Tester.txt * fix: deduplicate Fallback 4 'Diff' placeholder via seen set * chore: update non-Git mode copy to neutral 'changed in the last reply' * fix(chat): unify changes row with tasks --------- Co-authored-by: Bohdan Triapitsyn <artmore@protonmail.com>
