Rename local chat shortcut and surface terminal close hints

- Replace `chat.newSameGitState` with `chat.newLocal` across contracts, server/web defaults, docs, and tests
- Make `chat.new` preserve branch/worktree state while `chat.newLocal` creates a local thread
- Show terminal close shortcut labels in drawer action tooltips and tab close controls
