TUI:
- VimListView: j/k now move down/up in the project and session lists
(arrow keys still work); used by both list widgets.
tmux status bar:
- Widen the gap between window cells via a 2-space window-status-separator
(WINDOW_STATUS_SEPARATOR).
- Fix the current-window cell toggling between padded " 1: name " and
unpadded "1: name". The per-window status format is static, but
set_window_label re-asserted it on every 3s poll — letting a competing
writer (e.g. a stale TUI process running older code with a differently
padded format) flip the cell each cycle. The format is now owned by a
single write-once path (new_window at creation, apply_theme for existing
windows); the poll updates only the dynamic @hqt_label.
Also lands pre-staged scaffolding: AGENTS.md quality gate, TODO.md backlog,
and ty dev dependency.
