- Add verifyWithRetry to provisioner: 60s initial DNS propagation delay,
5 retries with 30s backoff before marking verification as failed
- Add GetNotifyDomainStatus: polls Resend API for domain verification status,
returns "not_configured" when Resend not set up
- Add VerifyProjectNotify: synchronous re-verification for handler use
- Add getDomainStatus to resendAPI interface + resendClient implementation
- Add NotifyDomainStatus domain struct (host, resend_domain_id, status)
- Guard NOTIFY_RESEND_DOMAIN_ID storage against empty string writes
- New handler: GET /projects/{id}/notify/status (returns verification state)
- New handler: POST /projects/{id}/notify/verify (triggers re-verification)
- Add verify-notify-domain cookbook step to persona-community,
slackpath-1, and slackpath-4 trees (polls status for up to 6 min)
