fix(tui): require explicit alt bit for escape-based alt chords

Hermes-ink reports bare Escape as meta=true+escape=true on some terminals, so a configured alt+escape binding was firing on bare Esc. Require an explicit key.alt bit when the configured named key is escape so plain Esc stays plain Esc; kitty-style alt+escape still fires.
