conjurer: add production ('deploy') bot + data seeding/backup

A second Conjurer bot alongside the test one, sharing librarian/musician/
radio and the API key, differing only in:
 * Discord token from the deploy-conjurer-netrc secret,
 * distinct names/labels (deploy-bot) and NodePort 32443,
 * /data on an NFS export (RWX) instead of a block PVC - so config/state
   can be uploaded while it runs (copy onto the share) and backed up
   concurrently.

deploy-bot-backup: a daily CronJob that mirrors /data and keeps 30 days of
dated snapshots of the critical small state (both memories, settings,
accident log, transcripts) on NFS. Production only - the test bot's
amnesia is fine. DEPLOY-BOT.md documents seeding, backup/restore, and the
librarian/musician callback routing (they push to one bot; repoint
CONJURER_MAIN_BOT to :32443 to feed this one).

kubectl kustomize builds cleanly (10 objects).

+# Production ("deploy") Conjurer bot.
+#
+# Same infrastructure as the test `bot` (shares librarian / musician / radio and
+# the CONJURER_API_KEY), with three deliberate differences:
+#   1. its Discord token comes from the `deploy-conjurer-netrc` secret,
+#   2. distinct names/labels so it coexists with the test bot in this namespace,
+#   3. /data is an NFS volume (RWX) instead of a block PVC - so config/state can
+#      be uploaded while the bot runs (just copy onto the share) and backed up
+#      concurrently (see deploy-bot-backup.yaml). The test bot keeps its RWO PVC.

+# ┌─ IMPORTANT: librarian & musician call ONE bot back ─────────────────────────┐
