🗑️ PERMANENTLY delete conversation thread(s) and their messages + user-facing state (tags, assignments, drafts, reminders, RAG chunks). Destructive and NOT undoable — requires confirm=true.
Pass thread_id for one, or thread_ids for a bulk delete. Kept intentionally: call history (voice_sessions), usage/billing, traces, and outreach dedup are NOT removed.
Note: for a live synced channel (Telegram/WhatsApp) this clears the LOCAL copy; a new inbound can re-create the thread on next sync. For livechat/voice/test/duel threads it's effectively permanent.
