Show HN: mailtrim – find what's actually filling your Gmail inbox

I always assumed Gmail bloat came from large attachments. Turns out 3 senders were responsible for 30% of my inbox — thousands of tiny emails I'd never thought to clean up.

I built mailtrim to surface this pattern:
- ranks senders by actual storage impact (not just count)
- confidence scoring on what's safe to bulk-delete
- 30-day undo on everything — nothing is permanent by default
- runs entirely locally, no email data leaves your machine
Free, open source (MIT). No subscription, no backend.
One friction point upfront: Gmail API setup is one-time, ~15 min.
After that it's just `mailtrim stats` and `mailtrim purge`.
Keen to hear feedback on the confidence/safety model especially —
that's the part I'm least sure I've got right.
