Root cause: a draft has no session_id, so use-slash-completions sent commands.catalog /
complete.slash with empty params and tui_gateway's _session_home_scope (session-only
profile_home) scanned the LAUNCH profile's skills; CompleteSlashParams also rejected a
`profile` key outright (extra=forbid -> 4000).
Fix: the hook sends the tile's routed profile when there is no session (cache keyed by
session-or-profile); _session_home_scope resolves a session-less `profile` through
_profile_home; `profile` added to CompleteSlashParams and SkillsReloadParams (same
session_id-or-empty shape in skills.reload) and the TS contract regenerated.
Red-on-base: tests/tui_gateway/test_protocol.py::test_sessionless_slash_palette_follows_profile_param
fails on origin/main (complete.slash -> 4000 "profile: Extra inputs are not permitted");
use-slash-completions.test.tsx "scopes a sessionless catalog and typed lookup to the routed
profile" fails on origin/main (commands.catalog called with {} not { profile }). Both green on head.
