[Profile] Add Nordic nRF52832 Hardware Constraints

[abduznik]

We need a hardware profile for the Nordic nRF52832 Bluetooth SoC. This is a great first issue for embedded developers familiar with Nordic's SoftDevice.

Task

Create a new file profiles/nrf52832.yaml.

Required Constraints

1. SoftDevice Timing: Warn against disabling global interrupts (__disable_irq()) for long periods (>50µs) as it kills Bluetooth connections.
2. Power: Flag busy-wait loops (while(flag);). Suggest __WFE() or sd_app_evt_wait().
3. Flash: Warn about writing to internal Flash directly while the radio is active.

Example

See profiles/stm32_f103.yaml for the format.
