v0.1.2

Removed

• The clean-cycle command — the Home Assistant button, the CLI clean-cycle
  subcommand, and commands.clean_cycle(). A live capture proved the inherited
  0x02A30000 ("cleanCycle") opcode resets the robot (odometerPowerCycles
  increments, no cycle runs) — it was a reset disguised as a cycle, so it's gone
  rather than left shipping a surprise reboot.

Changed

• 0xA3 reclassified to never-send. It's the reset / main-board-OTA
  orchestrator, not a motor command; the safety guard now refuses it unconditionally
  alongside 0xA4 / 0xAC / 0xAD. No motor command is exposed until a real
  cleanCycle trigger is recovered — the MOTOR / allow_motor gate stays wired but
  empty.
• Documented the action-command hunt in docs/reverse-engineering.md: the
  0xA3 correction, why the cleanCycle / power / empty / reset dispatch lives in a
  bootloader region absent from every public OTA image, the exhaustive (and empty)
  search for a complete firmware dump, and the recovery paths (cloud-byte capture,
  app decompile, ESP-flash / PIC-ICSP dump).
