Complete hci_uart_beacon build/flash/reset/UART workflow (user-provided commands):

# 1. Build
cd /home/paul/ncs/v3.0.2 && nrfutil toolchain-manager launch --ncs-version v3.0.2 -- west build --build-dir /home/paul/Documents/hci_uart_beacon/build /home/paul/Documents/hci_uart_beacon --board nrf54l15dk/nrf54l15/cpuapp

# 2. Flash
cd /home/paul/ncs/v3.0.2 && nrfutil toolchain-manager launch --ncs-version v3.0.2 -- west flash --build-dir /home/paul/Documents/hci_uart_beacon/build

# 3. Reset device
nrfutil device reset --serial-number 1050076061

# 4. UART capture (30s timeout)
timeout 30 minicom --device /dev/serial/by-id/usb-FTDI_C232HM-DDHSL-0_FTUD2ZB4-if00-port0 --baudrate 1000000

Notes:
- Use nrfutil toolchain-manager launch wrapper for NCS v3.0.2
- Board: nrf54l15dk/nrf54l15/cpuapp for nRF54L15
- Serial number for reset: 1050076061
- UART device: /dev/serial/by-id/usb-FTDI_C232HM-DDHSL-0_FTUD2ZB4-if00-port0
- Baudrate: 1000000 (matches UART configuration)
- Timeout 30s on minicom to auto-exit
- Start the UART and directly after that reset, to get the output
