Follow-up to the salvaged #66609 (4 primary readers) and #41604 (context
files): two more jobs.json readers rejected a BOM'd file —
- hermes_cli/backup.py _count_cron_jobs: a BOM made the count None,
silently disabling the post-update cron-loss auto-restore safety net
- agent/curator_backup.py _backup_cron_jobs_into: BOM broke the job
count (spurious parse_warning) and propagated the BOM into snapshots
Both now read utf-8-sig; curator snapshots are written BOM-free so
rollback restores a file load_jobs can read. AUTHOR_MAP entry added
for deacon-botdoctor.
Tests: BOM'd-live-file auto-restore + BOM'd snapshot count/BOM-free copy.
