Both hosts had live improvements the repo never recorded:
- esh-docker-vm excludes ESPHome's 539 MB of PlatformIO cache (2026-09-14).
- irv-ml1 runs /etc/restic/arbo-checkpoint.sh before the backup, a non-fatal
SQLite online-backup of arbo's gallery DB. That script is added here too.
The live copies were correct and are the source for the next change. (Also fixes
the fv-ml1 augaman removal time to ~0130 PT.)
