## Summary
- **Name/title mention notifications**: Amari now notifies Naomi when a message contains her name, common nicknames (`nomi`, `nao`, `nae`, `naonao`), or honorifics (`goddess`, `queen`, `mistress`, `your/her majesty`, `your/her highness`). Uses the same cooldown logic as mention forwarding.
- **Simplified mentee onboarding**: Replaced the lengthy welcome message with a concise prompt asking the new mentee to ping Naomi with their GitHub username and name.
- **Removed offboard notification**: `logMenteeLeave` now only logs a metric silently — no more "user must be offboarded" messages in the channel.
- **Deduplicated welcome messages**: Welcomed mentee IDs are persisted to `data/welcomed.txt` so the onboarding message is only ever sent once, even if the role is re-assigned.
## Test plan
- [ ] Assign mentorship role to a user and confirm the new onboarding message appears
- [ ] Re-assign the role to the same user and confirm no duplicate message is sent
- [ ] Remove a mentee from the server and confirm no offboard message is posted
- [ ] Send a message containing a matched name/honorific and confirm Naomi receives a DM forwarding it
