fix(tui): remove 'q' alias from /quit, add to /queue

The TUI frontend's slash command registry shadowed /queue's 'q' alias
with /quit's 'q' alias. Since /quit appeared later in the registry,
the flat lookup kept the later entry, making /q always quit instead
of queueing a prompt.

This mirrors the backend fix in PR #10538 (hermes_cli/commands.py)
but applies the same correction to the TUI TypeScript registry.

Fixes #10467
