1f59e52880
Added NRF52840 power management core functionality: - Boot‑voltage lockout - Initial support for shutdown/reset reason storage and capture (via RESETREAS/GPREGRET2) - LPCOMP wake (for voltage-driven shutdowns) - VBUS wake (for voltage-driven shutdowns) - Per-board shutdown handler for board-specific tasks - Exposed CLI queries for power‑management status in CommonCLI.cpp - Added documentation in docs/nrf52_power_management.md. - Enabled power management support in Xiao nRF52840, RAK4631, Heltec T114 boards
