Heartbeat POST now captures the response body (up to 2048 bytes) and looks for a "config" object. If cfg_version advances past the stored value and all tunable fields pass range validation, the new tuning is applied to g_cv and persisted to NVS. - cv_tuning_validate: pure range checker (cv.cpp) - cv_apply_tuning / cv_get_tuning: mutex-guarded helpers in main.cpp exposed via cv_apply.h; 500 ms timeout, drop on contention - post_json now returns int (HTTP status) and optionally captures the response body; existing callers check == 200 - heartbeat: parse → cfg_version check → override present fields → validate → apply → save. Silent no-op when server returns no config. - 3 new native tests (15/15 pass). timercam flash 1,423,897 bytes (+9,828 vs baseline).
