Description

Wire up command-mode single-key bindings, which only fire when the TUI is out of PTY focus (see impl-tui-modal).

Bindings:

'n' — new chat (replaces top-level Ctrl+N)
'w' — close current tab (remove from active list, NON-destructive — see impl-tui-tabs-as-view for semantics)
'0'..'9' — jump to tab N
Left/Right arrow — cycle tabs prev/next
'?' — show keybinding help overlay

Do NOT bind keys that conflict with existing command-mode features the user uses (e.g. if 'i' currently changes inspector width, leave it alone — note in research-tui-chat report).

Status bar should show available bindings briefly when entering command mode, or render a small hint line.

Validation

Failing test first: pressing 'n' in command mode dispatches new-chat action
'w' triggers close-tab (verify via close action emitted, not actual archive)
Number keys switch tabs
'?' opens help overlay listing all command-mode bindings
In PTY mode, none of these keys trigger TUI actions (covered by impl-tui-modal tests, but re-verify)
cargo build + cargo test pass
Live-smoke: launch TUI, Ctrl+T, press 'n', verify new chat tab appears
