* fix(bluebubbles): auto-create chats for new numbers, persist outbound messages to session transcripts
Two fixes for BlueBubbles message tool behavior:
1. **Attachment sends to new phone numbers**: sendBlueBubblesAttachment now
auto-creates a new DM chat (via /api/v1/chat/new) when no existing chat
is found for a handle target, matching the behavior already present in
sendMessageBlueBubbles for text sends. The existing createNewChatWithMessage
is refactored into a reusable createChatForHandle that returns the chatGuid.
2. **Outbound message session persistence**: Ensures outbound messages sent
via the message tool are reliably tracked in session transcripts:
- ensureOutboundSessionEntry now falls back to directly creating a session
store entry when recordSessionMetaFromInbound returns null, guaranteeing
a sessionId exists for the subsequent mirror append.
- appendAssistantMessageToSessionTranscript now normalizes the session key
(lowercased) when looking up the store, preventing case mismatches
between the store keys and the mirror sessionKey.
Tests added for all changes.
* test(slack): verify outbound session tracking and new target sends for Slack
The shared infrastructure changes from the BlueBubbles fix (session key
normalization in transcript.ts and fallback session entry creation in
outbound-session.ts) already cover Slack. Slack's sendMessageSlack uses
conversations.open to auto-create DM channels for new user targets.
Add tests confirming:
- Slack user DM and channel session route resolution (outbound.test.ts)
- Slack session key normalization for transcript append (sessions.test.ts)
- Slack outbound sendText/sendMedia to new user and channel targets (channel.test.ts)
* fix(cron): skip stale delayed deliveries
