Replace webklex/php-imap with directorytree/imapengine in the ticket email parser. ImapEngine is pure PHP over sockets. Parser improvements: - Wrap per-message processing in try/catch so one malformed email can't abort the run; failures are flagged and logged with UID - Query unseen + unflagged so previously-failed (flagged) messages are no longer re-processed on every cron run - Skip vacation/auto-responder emails (RFC 3834) to prevent mail loops with the ticket auto-reply - Cap messages per run (50) and attachment size (15MB); inline images over 2MB are stored as attachments instead of base64-embedded in ticket details - Atomic lock file creation - preg_quote() the ticket prefix in subject matching - Dedupe CC watchers and exclude the sender - Map webklex 'tls' encryption setting to STARTTLS for compatibility NDR/DSN parsing now walks MIME parts via the underlying zbateson parser instead of relying on attachment extraction.
