fix(openclaw): prevent memory wipe on every session (#323)

Browse source 
Use unique document_id per conversation (sessionKey + timestamp) instead
of static sessionKey. The backend CASCADE-deletes old memories when the
same document_id is reused, causing all prior facts to be lost.

Also:
- Universal envelope stripping for all channels (was Telegram-only)
- Prefer rawMessage over prompt for cleaner recall queries
- Increase recall max_tokens from 512 to 2048
