Don't install this :)
DEV purposes only!
Changes since v0.0.4:
- Fix OTA install aborting on single-card devices (phantom second SD slot mountpoint). OTA now arms only genuinely mounted SD roots, secondary best-effort.
Carries all prior fixes: first-install set (auto-sleep, Wi-Fi PMF, reboot/power-off, exit-to-stock, charging CPU, Wi-Fi off), default Leaf look, bundled CA roots for OTA TLS, installed-version in About.
