evan.liu 8a7cebcf77 V1.00.26: UART baud 115200 -> 460800

- firmware BSP_USART_BAUDRATE 460800 (divider error +0.03%); uartrst/
  uartinfo follow the macro
- RX DMA ring 2KB -> 3KB: at 460800 2KB only covers 44ms, less than the
  ~45ms flash-erase interrupt-off window; stack top now 0x2000BDE8
  (guard warns <1KB from the 0x2000C000 cliff, by design)
- tools: ble_ota_update.py UartTransport and uart_cap.py default baud
- Verified: stream OTA 55832B in 2.6s @23kB/s (one lost frame recovered
  by go-back-N), PASS after reboot; text CLI fine at 460800
- docs: ble_protocol.md, design spec, AGENTS.md, dev log section 48
