A required-args slash command submitted bare (/model, or /m) ran straight
into its usage error. The completeness contract already existed —
is_command_complete's documented 'Blocks' row — but had zero non-test
callers; both dispatch paths ran the command unconditionally.
Both the session prompt path and the dashboard dispatch box now consult
is_command_complete before running: an incomplete required-args command
re-opens the input as '/{command} ' with the cursor in the args phase, so
the existing suggestion dropdown lists the choices (for /model: the
catalog — by construction the connected providers' models, after
1bb10ef). Generalizes to every future required-args command; no new UI.
Verified: kigi-tui 6872 tests green, clippy clean.
