// src/commands/jiraPoll.js
//
// /jirapoll        — run the hourly Jira poller ON DEMAND. Same code
//                    path as the cron job. Enriches any unlabeled
//                    matching tickets with a phone/av snapshot comment,
//                    labels them, and posts the standard summary to
//                    JIRA_POLLER_ROOM_ID if any were enriched. Also
//                    replies in the invoking chat with the counts so
//                    you get immediate feedback.
//
// /jirapoll prime  — run in PRIME mode (labels every matching ticket
//                    without enriching or notifying). Equivalent to a
//                    one-off JIRA_POLLER_PRIME_ON_START=true restart.
//
// Auth model
//   The command is `mutating: true` in the registry, so hitting the
//   HTTP path requires HTTP_API_TOKEN. From Webex chat any user who
//   can talk to the bot can run it — same trust model as the other
//   mutating chat commands (`offboarduser`, `webexhost`, etc.).
//
// Concurrency
//   `pollNewTickets` uses Jira labels for idempotency, so overlapping
//   invocations are safe (each ticket can only be enriched once). If
//   two people trigger `/jirapoll` at the same second, they'll each
//   process disjoint slices of the label-race — no double comments.
