Review and the single-file view gain per-hunk Stage and Undo
(stage-hunk / discard-hunk: the hunk is named by its @@ line and
re-matched against a fresh diff, then git apply --cached / -R; undo
needs confirm: true and two clicks). Each review file header stays
pinned while its diff scrolls and carries the file's own
stage/unstage/discard.
- The Changes panel's width control gains a full-width step (narrow →
50/50 → 70/30 → full → closed); the console beside it is hidden with
CSS, never unmounted.
- "Expand all folders" is one GET /api/lanes/:id/git/tree-all (one
`git ls-files`, every level shaped like /git/tree) instead of one
request and one git process per folder.
- Overview: a Stage all button and the staged-only commit box sit above
the file list and stay pinned while it scrolls; the Files finder is
pinned too.
- Changes card beside lane detail with five modes: Files tree, overview,
Review (whole diff, per-file collapse), single file, commit history.
- LaneDiffView: unified / side-by-side with independent scroll on both axes
and mirrored scrollLeft, expand/collapse context, intra-line emphasis.
- Staged-only commit box; git actions (fetch/pull/push/stage/unstage/
discard/commit/switch/branch-create/branch-delete) guarded in git-ops.js.
- Server: git-diff.js + git-ops.js behind GET /api/lanes/:id/git/* and
POST /api/lanes/:id/git/:action; gitFacts gains upstream/ahead/behind.
- Add lane: new/existing branch, current branch, worktree list, prefill
from the git bar's "New lane here"; /api/run/cwds gains a repo kind.
- GlobalTooltip upgrades every native title into a themed anchored bubble;
chart/info popovers use theme tokens.
