How AI was used in this PR

Claude implemented the changes following my spec.

Proposed Changes

• Add Dolly CLI bump-stat groups and metrics for start, attach, turn outcomes, detach reasons, and weekly/monthly unique usage.
• Emit those stats from the remote-session start and poll-loop lifecycle, respecting --avoid-telemetry in foreground and daemon modes.
• Add poll-loop tests covering telemetry opt-out, successful attach/turn/detach bumps, turn status mapping, and auth-error detach classification.

Testing Instructions

• Build the CLI with the NPM config using npm run cli:build:npm
• Open ~/.studio/cli.json and delete the lastBumpStats object
• Run remote sessions in the foreground NODE_ENV=development node apps/cli/dist/cli/main.mjs code remote-session start --no-detach
• Check that you see "Would have bumped stat" messages in the log for the newly added stat groups
  
• Optionally do a turn through Telegram
• Check that in ~/.studio/cli.json, the stats are populated under lastBumpStats

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Thanks @gcsecsey for adding those, they will be very helpful to get feedback! I have tested it, and I can see the stats bumped, while they don't appear when using --avoid-telemetry. Changes also LGTM!

Question about naming, are there any other occurrences of Dolly, if not, should we adopt the wp-agent naming? 🤔

Thinking again about this, I think it's fine to consider Dolly as the internal codename
