Dockerises the radio_conjurer.liq environment on Debian bookworm: - Dockerfile.radio builds Liquidsoap through opam with build args for OPAM_VERSION (static binary), OCAML_VERSION (default 4.14.2; 2.1.x needs OCaml 4.x - prod ran 4.13.0, pass it for parity) and LIQUIDSOAP_VERSION (default 2.1.4, matching the script) - LIQ_OPAM_PACKAGES installs exactly the features the script uses: mad+lame (mp3), cry (icecast), taglib (tags/replaygain), pulseaudio (mic/out), samplerate, inotify (watch-reload), ffmpeg - ffmpeg.pref verdict: the Pi pin forced Debian's FFmpeg 5.x family (libavcodec59...) over RPi OS repo builds because the ocaml-ffmpeg bindings are compiled against those sonames; bookworm ships them natively so the container needs no pin (documented, not copied) - pulse-access/audio group memberships baked in (were manual on the Pi); PULSE_MODE=internal runs a system-wide pulse with a null sink so the unmodified script works on a headless VM (mic = silence), host mode mounts the real socket, none for edited scripts - mounts mirror the script's hardcoded paths (/home/pi/Conjurer, /home/pi/MediaFolder/mp3) so radio_conjurer.liq runs unmodified; entrypoint seeds script+params on first run (never overwrites), creates missing playlists, seeds placeholder icecast credentials (loud warning) and generates a silent emergency mp3 when the single() file is missing - compose.radio.yaml: extra_hosts maps the script's host="radio" to ICECAST_HOST_IP; exposes 54321 (bot's RADIO_HARBOR /skip) and 9999 - docs: radio section with build args, pulse modes and the ffmpeg.pref / groups verdicts Part 2 of this PR (splitting bot<->radio comms out of the musician into a radio+betoniarka container) follows on this branch.
