feat(messaging-ui): import a channel's roster from the settings panel

Phase C of channel-roster import. Adds the optional addMembers(threadId, userIds) adapter seam (+ BulkAddResult) and, in ConversationSettings, a '#' mode on the existing Add-people box that lists the channels you belong to — public AND private, since the source list is your own membership-scoped conversation list. Picking a channel STAGES the import (reads its roster, diffs against who is already here) and shows a confirm — 'Add 9 people from #design? (3 already here)' — so an administrative action never fires on a stray click. The result line reports added / already-a-member / failed. Absent addMembers => the affordance is hidden entirely and '#' is just a search string. Bumped to 0.1.8. SDK suite: 15 files / 78 tests green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
