feat(tui-go): command-palette keybinds + configurable status bar

Palette: each command now shows its bare-key shortcut in a key column (and the filter
matches on it), so the palette teaches the shortcuts instead of hiding them.

Status bar: a new "status bar" palette command opens a toggle overlay to show/hide the
non-essential segments (current stage, session status, workspace path, model, last-event
clock, resource gauge); correx/connection/session-name/spinner stay. Choices persist
TUI-local in tui-prefs.json (JSON in the config dir — display state, kept out of the
shared/replayed server config) and reload on launch.

Also trims the in-session footer (drops stats/model — both reachable via `p cmds`) so it
no longer overflows + truncates `q quit` at ~100 cols after the transcript-nav additions.
Tests cover toggle→render gating and prefs persistence; verified via cmd/preview renders.
