work/immich_stage.py: - Startup probe of /server/version (exit 2 if unreachable). - Outage circuit breaker: after OUTAGE_FAIL_STREAK=12 consecutive faces_error/download_error results, run a quick probe; if the probe also fails, persist state and exit with code 2 so a long unattended run can pause rather than silently churning through tens of thousands of retries during an upstream outage. Resume by re-running the same command -- state.json + queue.json are intact. README: - Document the nic run (per-user API key necessary; second pipeline invocation confirmed expected behavior; cleaner library than peter's with 0 internal byte-dupes vs 2,976). - Mention the circuit breaker as the mechanism that keeps long unattended runs safe under the known Tailscale flicker pattern at this site.
