Every build now records at boot which version runs and, after a crash restart, which one crashed (even across a Rollback). The core dump summary (task, PC, reason, backtrace) is printed and raised as a Notification; `crash` shows it later. After 3 crash restarts in a row the firmware starts in Safe Mode: clock, Wi-Fi, Update Service and Debug Console only (SafeMode, 2 host tests). A normal restart or a minute up resets the count. The main loop is now on the task watchdog (enableLoopWDT): Arduino only watched core 0's idle task, so a stuck loop hung the device for good. The Update Service restarts into an installed update by itself if the main loop hasn't after 90 s. Debug Builds: `coredump get` and `reset` are answered by the console's own task; rdbg.py crash decodes the backtrace and rdbg.py coredump runs esp-coredump, against ELFs archived by version and digest in .pio/elves. The StorageService mutex is now made in the constructor: Safe Mode never starts that Service, and `info` crashed on the null mutex, 29 times in a row before the fix was pushed into Safe Mode over Wi-Fi. Verified on the device: crash report and full core dump decoded over Wi-Fi; Safe Mode at exactly 3 crashes, left by `reboot`; a hung loop caught by the watchdog in 5 s; `reset` from the console task.
