CMakeLists.txt: generate firmware.map via -Wl,-Map.

CI build job:
- Writes per-section size table to the Gitea job summary
  (visible in the Actions UI after each run).
- Uploads firmware.hex and firmware.map as a downloadable artifact
  named firmware-<sha>.

CI docs job:
- On push to main, force-pushes docs/html/ as an orphan commit to
  the gh-pages branch.  Gitea Pages must be enabled in site admin
  for the HTML to be served; the branch is always available via the
  repo file browser regardless.

438fca0ace Initial bare-metal foundation for nRF52840 PTT-FHSS 
- Fully open toolchain: arm-none-eabi-gcc inside Podman/Docker container
- Platform-agnostic build via justfile (auto-detects podman vs docker)
- CMake + Ninja build system with arm-none-eabi toolchain file
- nRF52840 linker script and startup with full 64-entry vector table
- Register access via typed bitfield unions (include/regs.h)
- FHSS channel sequencer: AES-128-ECB PRNG over 40 channels (2402-2480 MHz)
- Low-power sleep via SYSTEM_ON WFI + GPIOTE wakeup on button press
- Vendor deps as shallow git submodules: nrfx, CMSIS_5, tiny-AES-c
