feat(tui): add /skills: sub-completion in autocomplete

Typing /skills: in the prompt now triggers inline autocomplete for
skill names instead of opening the full dialog. Skills are listed
alphabetically and filtered via fuzzysort as the user types after
the colon. Selecting a skill inserts /<skill-name> into the prompt.
