mangavalkandClaude Opus 5.5 a8f6bb3ca5 Fit this lamp: 4 alarms, full data model, knock snooze, server use
Decode DP127 as 48 bytes (4 alarms), plus DP128, DP107 and DP126, from Tuya's
data model. Add day switches, alarm and sunset controls, a knock sensor on PA18,
display schedule, bedtime fade, radio timer and grouped web UI. Pin LibreTiny
v1.14.0 for the OTA restart fix. Ship the patched UART as an external component
so a server needs only a short YAML.
