28c934deff 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)

dd4eabf218 fix: Investigate USB CDC TX failure (Issue #524)
Root causes confirmed from code audit:
1. DCache coherency: USB OTG FS reads physical SRAM while CPU writes through
   DCache. Fix: MPU Region 0 marks 512B aligned USB buffer struct non-cacheable
   (TEX=1, C=0, B=0) before HAL_PCD_Init(). DCache stays enabled globally.
2. IWDG ordering: safety_init() (IWDG start) deferred after all peripheral inits
   to avoid watchdog reset during mpu6000_calibrate() (~510ms blocking).

DMA conflicts, GPIO conflicts, clock tree, and interrupt priorities all ruled out
with evidence. Full findings documented in USB_CDC_BUG.md.
