Deterministic deployment instead of agent ritual:
- DROP_CACHES per target (dankclaw=1): runs 'sync; echo 3 >
/proc/sys/vm/drop_caches' before systemctl restart. Without it the
model load stalls at 28 GiB VRAM when the model pages are cached.
- FRANK_SUDO_PW env var: remote sudo pipes it via 'sudo -S' so the
script runs headless. Falls back to plain sudo otherwise.
- Health check runs curl on the target over ssh (127.0.0.1:7770 was
previously checked from the workstation, which can never see it).
