291dd689f8 feat: remove all STM32/Mamba/BlackPill references — ESP32-S3 only
Archive STM32 firmware to legacy/stm32/:
- src/, include/, lib/USB_CDC/, platformio.ini, test stubs, flash_firmware.py
- test/test_battery_adc.c, test_hw_button.c, test_pid_schedule.c, test_vesc_can.c, test_can_watchdog.c
- USB_CDC_BUG.md

Rename: stm32_protocol → esp32_protocol, mamba_protocol → balance_protocol,
  stm32_cmd_node → esp32_cmd_node, stm32_cmd_params → esp32_cmd_params,
  stm32_cmd.launch.py → esp32_cmd.launch.py,
  test_stm32_protocol → test_esp32_protocol, test_stm32_cmd_node → test_esp32_cmd_node

Content cleanup across all files:
- Mamba F722S → ESP32-S3 BALANCE
- BlackPill → ESP32-S3 IO
- STM32F722/F7xx → ESP32-S3
- stm32Mode/Version/Port → esp32Mode/Version/Port
- STM32 State/Mode labels → ESP32 State/Mode
- Jetson Nano → Jetson Orin Nano Super
- /dev/stm32 → /dev/esp32
- stm32_bridge → esp32_bridge
- STM32 HAL → ESP-IDF

docs/SALTYLAB.md:
- Update "Drone FC Details" to describe ESP32-S3 BALANCE board (Waveshare ESP32-S3 Touch LCD 1.28)
- Replace verbose "Self-Balancing Control" STM32 section with brief note pointing to SAUL-TEE-SYSTEM-REFERENCE.md

TEAM.md: Update Embedded Firmware Engineer role to ESP32-S3 / ESP-IDF

No new functionality — cleanup only.

49628bcc61 feat: Add Issue #507 - Face display animations on STM32 LCD
Implements expressive face animations with 5 core emotions (happy/sad/curious/angry/sleeping) and smooth transitions on small LCD displays.

Features:
- State machine with smooth 0.5s emotion transitions (ease-in-out cubic easing)
- Automatic idle blinking (4-6s intervals, 100-150ms duration per blink)
- UART command interface via USART3 @ 115200 (text-based protocol)
- 30Hz target refresh rate via systick integration
- Low-level LCD abstraction supporting monochrome and RGB565
- Rendering primitives: pixel, line (Bresenham), circle (midpoint), filled rect

Architecture:
- face_lcd.h/c: Hardware-agnostic framebuffer & display driver
- face_animation.h/c: Emotion state machine & parameterized face rendering
- face_uart.h/c: UART command parser (HAPPY/SAD/CURIOUS/ANGRY/SLEEP/NEUTRAL/BLINK/STATUS)
- Unit tests (14 test cases): emotion transitions, blinking, rendering, all emotions

Integration:
- main.c: Added includes, initialization (servo_init), systick tick, main loop processing
- Pending: LCD hardware initialization (SPI/I2C config, display controller setup)

Files: 9 new (headers, source, tests, docs), 1 modified (main.c)
Lines: ~1450 total (345 headers, 650 source, 350 tests, 900 docs)
