cea3eaff97 cleanup: Remove all Mamba/STM32/BlackPill references — ESP32-S3 only
- Renamed mamba_protocol.py → balance_protocol.py; updated all importers
- can_bridge_node.py rewritten to use balance_protocol.py API (ESP32-S3 BALANCE)
- test_can_bridge.py rewritten to test actual balance_protocol.py constants/functions
- All STM32/Mamba references in Python, YAML, Markdown, shell scripts replaced:
  * Hardware: MAMBA F722S → ESP32-S3 BALANCE/IO
  * Device paths: /dev/stm32-bridge → /dev/esp32-io
  * Node names: stm32_serial_bridge → esp32_io_serial_bridge
  * hardware_id: stm32f722 → esp32s3-balance/esp32s3-io
- C/C++ src/include/lib/test files: added DEPRECATED header comment
- Covers: saltybot_bridge, saltybot_can_bridge, saltybot_can_e2e_test,
  saltybot_bringup, saltybot_diagnostics, saltybot_mode_switch, and all
  chassis, docs, scripts, and project files

c348e093ef feat: Add cooling fan PWM speed controller (Issue #263)
Implements STM32F722 driver for brushless cooling fan on PA9 using TIM1_CH2 PWM.
Features:
- Temperature-based speed curve: off <40°C, 30% at 50°C, 100% at 70°C
- Smooth speed ramp transitions with configurable rate (default 0.05%/ms)
- Linear interpolation between curve points
- PWM duty cycle control (0-100%)
- State transitions and edge case handling

All 51 unit tests passing:
- Temperature curve verification (6 test zones)
- Speed boundaries and transitions
- Ramp timing and rate control
- PWM duty cycle calculation
- Temperature extremes and boundary conditions
