- Fire commitment_accepted/commitment_declined notifications when solver
results are accepted/rejected in intent-routes.ts
- Fire commitment_declined when a connection is deleted in mod.ts
- Add metadata (resultId, fromCommitmentId) to commitment_requested notify
- Fix actionUrl to use /rtime (subdomain-relative), not /{space}/rtime

commitment_requested events (same pattern as space_invite)
