feat(arch): migrate all STM32/Mamba/BlackPill refs to ESP32 BALANCE/IO + fix roslib@1.4.0
Architecture change (2026-04-03): Mamba F722S (STM32F722) and BlackPill replaced by ESP32 BALANCE (PID loop) and ESP32 IO (motors/sensors/comms). - Update CLAUDE.md, docs, chassis BOM/ASSEMBLY, pinout, power-budget, wiring-diagram, TEAM.md, AUTONOMOUS_ARMING.md, docker-compose - Update all ROS2 package comments, config labels, launch args (stm32_port→esp32_port, /dev/stm32-bridge→/dev/esp32-bridge) - Update WebUI: stm32Mode→esp32Mode, stm32Version→esp32Version, "STM32 State/Mode" labels → "ESP32 State/Mode" (ControlMode, SettingsPanel) - Add TODO(esp32-migration) markers on stm32_protocol.py and mamba_protocol.py binary frame layouts — pending ESP32 protocol spec from max - Fix roslib CDN 1.3.0→1.4.0 in all 11 HTML panels (fixes ROS2 Humble rosbridge "Received a message without an op" incompatibility) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

1. **SysTick_Handler with HAL_IncTick() is MANDATORY** — without it, HAL_Delay() and every HAL timeout hangs forever. This bricked us multiple times.

2. **DCache breaks SPI on STM32F7** — disable DCache or use cache-aligned DMA buffers with clean/invalidate. We disable it.

2. **DCache breaks SPI on ESP32** — disable DCache or use cache-aligned DMA buffers with clean/invalidate. We disable it.
|
||||
3. **`-(int)0 == 0`** — checking `if (-result)` to detect errors doesn't work when result is 0 (success and failure look the same). Always use explicit error codes.
|
||||
4. **NEVER auto-run untested code on_boot** — we bricked the NSPanel 3x doing this. Test manually first.
|
||||
5. **USB CDC needs ReceivePacket() primed in CDC_Init** — without it, the OUT endpoint never starts listening. No data reception.

[15:8], [7:0]. This Python implementation replicates that behaviour.
