c22b81dfba feat(can): update CAN 0x75 control frame layout for 16-bit speed and led_r/led_l
- can_ctrl_cmd_t.speed: uint8_t -> uint16_t (bytes 0-1, little-endian)
- Remove led_gpio field; add led_r (byte7 bit0) and led_l (byte7 bit7)
- byte6 now carries only led_enable (bit0), not the old gpio/enable packed format
- Update keepalive thread and can_bus_send_control_cmd() frame assembly accordingly
- Update all 6 can_ctrl_cmd_t call sites in event_recorder.c and app_header_init.c
- test_can_event() parameter type: uint8_t speed -> uint16_t speed

fd54f5cc0b feat(can/rx): MCP2515 CAN RX interrupt thread for ECU ID 0x50
- can_bus.h: add can_ecu_status_t struct + can_bus_get_ecu_status() declaration
- can_bus.c: add gpio_interrupt_init() (gpio sysfs, falling-edge poll)
- can_bus.c: add can_rx_thread() - poll gpio63 INT pin, parse 0x50 frame
  (throttle_status, pedal_volt, led_flash_timer, can_lose_ecu, throttle_limit_off, heart_beam)
  with CAN_LOSE timeout detection (100ms)
- can_bus.c: start/join can_rx thread in can_bus_init()/can_bus_close()
- can_bus.c: add can_bus_get_ecu_status() thread-safe snapshot

e108bfe13a feat(can): add LED control fields to can_ctrl_cmd_t, CAN speed in fire_* callbacks
- can_bus.h: add can_ctrl_cmd_t struct (speed/led_gpio/led_enable/keepalive_interval_ms)
- can_bus.c: rename s_keepalive_cmd->s_keepalive_speed; add s_keepalive_led_gpio/
  led_enable/interval_ms; keepalive thread supports LED blink (toggle when
  led_enable=1) and dynamic interval; remove #define CAN_KEEPALIVE_INTERVAL_MS
- event_recorder: fire_collision_warning sends SPEED_LIMIT_STOP/NORMAL via CAN
- event_recorder: fire_alert sends SPEED_LIMIT_ALERT/NORMAL via CAN
- event_recorder/app_header_init: update callers to use can_ctrl_cmd_t struct
