Marrow v0.14.0

Review a PR entirely from the keyboard. This release adds a diff line cursor and the full set of review actions on top of the navigation shortcuts from v0.12–v0.13. Press ? in any review for the complete cheatsheet.

New: Keyboard-driven reviewing

• Line cursor: j / k move a highlighted cursor through the diff and the view follows; g / G jump to the top/bottom; Ctrl+D / Ctrl+U and Space / PageUp·PageDown page it. Works in both split and unified views.
• Comment & select: c comments the cursor line; v starts a selection you extend with j / k, then c comments the whole range — on the correct side.
• Reply & resolve: with the cursor on a line that has a review thread, r opens a reply box and x resolves / reopens it.
• Submit a review: R opens a picker — approve, request changes, or comment — type the body and send, no mouse needed.
• Hunks & AI notes: } / { jump between hunks, n / N between AI notes; z folds the hunk at the cursor (and the cursor can land on a collapsed hunk to expand it again), Z folds/unfolds everything.
• Switch PRs: Ctrl+Tab and Ctrl+Shift+Tab cycle between your open tabs.
