Adds CVTuning to CVState, populates defaults from existing file-scope
constants in cv_init, and introduces config_load_tuning/config_save_tuning
backed by the doorcounter NVS namespace. No runtime behavior change yet;
CV code still reads the existing constants (Task 2 will migrate reads).

- 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

loopTask: cv_init() created a CVState{} temporary (9KB background
array) on the stack — fixed by initializing members directly.
cam task: cv_process() had uint8_t fg[CV_PIXELS] (9KB) as a local
variable — made static, matching the existing fg_copy fix.
cam task stack bumped from 4096 to 8192 for headroom.
Also: switch to 4MB OTA partition table (TimerCamera-F has 4MB flash,
not 8MB), add CONFIG_ARDUINO_LOOP_STACK_SIZE=16384 build flag,
upload_speed=115200 and --no-stub for reliable CH340 flashing.

- hmac_sign now takes method+path instead of device_id; builds message as
method\npath\ntimestamp\nhex(sha256(body)) per server verify_device_hmac
- reporter: header renamed X-HMAC-Signature → X-Signature; passes "POST"+path
- test vector regenerated against new message format; timestamp-diff test updated
- .size() → .length() throughout (Arduino String has no size())

Add camera.h/camera.cpp for TimerCamera-F OV3660 init and box-filter
downscale to 96x96 grayscale. Add espressif/esp32-camera to lib_deps.

Replaces empty stub with full application: camera+CV task on core 1 at
5 fps, hourly reporter task on core 0, WiFi reconnect loop, 5-second
factory reset via BOOT button (GPIO37), LED on GPIO2 for status.

- reporter_submit_camera/ble: cap batch to REPORTER_MAX_BUFFER before
POST and assign whole capped batch back to buffer on failure, fixing
silent record drop when batch > buffer capacity
- post_json: reject sends when ts < 1700000000 (clock not NTP-synced)
- post_json: add comment documenting intentional no-cert-validation

Add passive BLE scan module using NimBLE for WiFi coexistence. Tracks
unique devices per hour with SHA256-hashed MACs, RSSI bucketing
(near/mid/far), max concurrent count, and thread-safe collect/reset.

Add BFS flood-fill blob extraction, centroid finding, and nearest-neighbour track matching/spawning inside cv_process. Add test verifying a new blob spawns a track.

Replace short-circuit boolean evaluation of putString return values with
separate size_t variables so both writes always execute regardless of
whether the first succeeds.
