When a blob briefly drops below CV_MIN_BLOB_PX, its track is killed and respawns,
causing the same person to generate multiple counts per visit (~50/min observed
in field). Add a per-direction cooldown (default 5 frames ≈ 0.8s @ 5 fps) that
drops subsequent entries (or exits) within the window of the last counted one.
Entry and exit cooldowns are tracked independently.
Fixed at compile time for now; exposing as a server-push tunable is deferred
until the server-push-config branch lands. See docs/server-prompt-crossing-
cooldown.md for the server-side coordination notes.

- Reduce debug level to 1 (errors only) for production builds
- Replace BLE pause/resume with full deinit/reinit during HTTP uploads (~25KB freed)
- Add 60s boot report delay for fast post-deploy connectivity verification
- Add device_id to BLE batch and heartbeat request bodies
- Correct API host to http:// (plain HTTP, not HTTPS)
- Add HTTP response logging and CV entry/exit serial logging
- Create root README.md with operator setup and architecture overview
- Update design spec: HMAC format, BLE memory approach, request body shapes, reporting intervals
