- Lift duplicated identity-gen block from main_companion.cpp + main_repeater.cpp into ZephyrRNG::generateFirstBootIdentity(). Both mains shrink from ~40 lines to a 3-line helper call. - Add LocalIdentity::fromSeed() so seed-derived keygen doesn't need a one-shot RNG wrapper; delete SeededRNG. - Drop the per-byte ADC sampling loop: getBattMilliVolts() does an 8-sample average + 10ms regulator settle internally, costing 300-480ms of real wall-time and actively destroying the LSB jitter it was meant to harvest. Jitter mixer already dwarfs it. - Centralize the printk + sys_reboot pattern as Utils::cryptoPanicReboot(); drop the 2000ms pre-reboot k_msleep (printk is synchronous, sleep just blocked the mesh thread on the ZephyrRNG::random() retry-failure path). - Inline sample_cpu_jitter health check via online scalars instead of a 512-byte deltas[] array. Saves 1.5KB stack churn across boot and tracks every sample instead of only the first 128. - extract_via_aes_ctr now uses Utils::sha256 instead of open-coding psa_hash_compute.
