q 8d7721c775 B7: add network time bootstrap and persistent B7C cache 
B7A: QMI DMS time vs VNIIFTRI NTP (DMS = UTC - 0.28 s, sigma 1 ms; NITZ = DMS
truncated to 1 s). B7B: a 1970 -> 2026 date -s step is harmless for the modem
stack. B7C: aurora-modem probes DMS/NITZ along the start flow and steps
CLOCK_REALTIME once at the first valid sample (REG registered/attached), never
RTC; background SNTP check (query only) after START OK. 3/3 class-A cold boots
PASS (residual +0.04/+0.36/+0.84 s), cache 14fe453a written (B7C_WRITE_VERIFIED)
and verified by a normal power-on (V1, +0.26 s).

Also publishes the prerequisite R2 (boot-hang / lk eMMC investigation, T4
telnet baseline that B7C builds on) and R3 (autonomous cold boot, NCM loss)
material, and extends tools/publish-sanitize.py to r2/, r3/, b7/.
Binary images, initramfs, busybox and raw logs stay out (see b7/*/SHA256SUMS).
