Session tools (sessions_list, session_status, sessions_history, sessions_send)
were using resolveAgentIDString(ctx) which returns the agent UUID, but session
keys are built using agent_key. This caused all session tool operations to fail
silently or return "access denied" for every channel.
Replace resolveAgentIDString() with ToolAgentKeyFromCtx() in all four session
tools. Add fail-closed guard for empty agent key.
- Enable merge UI for linking channel contacts to tenant_users
- Contact → tenant_user resolution with cached lookup (60s TTL)
- MCP per-user credentials via user-keyed connection pool
- Secure CLI per-user credentials with AES-256-GCM encryption
- Unified UserPickerCombobox searching contacts + tenant_users
- Group contact collection with chat title in all channels
- Group permission inheritance via wildcard user_id="*"
- Fix heartbeat using wrong userID in group chats
- Filter internal senders from contact collection
- Add contact_type column (user/group) to channel_contacts
- SQLite schema v2 migration for desktop edition
- session_status: GetOrCreate → Get to prevent phantom session creation
- sessions_history: replace string concat with json.Marshal (2 paths) to prevent JSON injection
- sessions_send: use s.Label from List() directly (eliminates N+1 Get calls), add self-send protection, use json.Marshal for response
- All tools: fail-closed agentID check (error when empty instead of skipping validation)
- Add 22 unit tests covering all session tools
