feat(install): support Raspberry Pi OS Bookworm (Python 3.11) alongside Trixie (3.13) (#689)

Browse Source 
The installer and scripts/check_system_compatibility.sh share one set of OS rules (scripts/install/lib_os.sh): Bookworm (Debian 12, Python 3.11) and Trixie (Debian 13, Python 3.13) are supported, python3 older than 3.11 stops the install before anything changes, and dhcpcd gets a warning with directions. setcap targets /usr/bin/python3, the apt fallback honours the requirement floors, and the desktop check no longer misreads under pipefail. CI runs the unit and plugin-safety suites on 3.11 and 3.13 (tooling jobs on 3.13); mypy targets 3.11.

- **1GB models (Pi 3B / 3B+), the 512MB Pi Zero 2 W and other low-memory boards**: supported, but the `rpi-rgb-led-matrix` C++ build needs more memory than the Pi has. The installer detects this automatically, compiles with fewer parallel jobs, and adds a temporary swapfile for the build which it removes afterwards. Expect that step to take 15-25 minutes instead of 2-5, and leave at least **3GB free** on the SD card. If you manage swap yourself, opt out with `--skip-swap`. To pin the compiler down further, use `--build-jobs 1`. Once running, keep an eye on memory: see [docs/LOW_MEMORY_BOARDS.md](docs/LOW_MEMORY_BOARDS.md).
### Operating system
- **Raspberry Pi OS Lite, Trixie (Debian 13) or Bookworm (Debian 12)**, 64-bit recommended. Trixie is the current release and the one to pick for a new SD card; an existing Bookworm install works as it is, no upgrade needed. The installer checks this first and stops with directions on anything else (Bullseye and older, the desktop edition, other distributions).
- **Python**: whatever the OS ships, 3.13 on Trixie and 3.11 on Bookworm. Don't install a different Python; the installer and the services use the system `python3`.
- **Networking**: NetworkManager, the default on both. Choosing a WiFi network from the web page and the `LEDMatrix-Setup` hotspot need it; if you switched to dhcpcd in `raspi-config`, switch back (Advanced Options → Network Config → NetworkManager).
### RGB Matrix Bonnet / HAT
- [Adafruit RGB Matrix Bonnet/HAT](https://www.adafruit.com/product/3211) – supports one “chain” of horizontally connected displays
- [Adafruit Triple LED Matrix Bonnet](https://www.adafruit.com/product/6358) – supports up to 3 vertical “chains” of horizontally connected displays *(use `regular` as hardware mapping)*
