Subject: docker: build and run on Debian trixie

Add a multi-stage image that compiles inside Debian trixie and runs on the
same glibc/libssl/libopus, avoiding the Arch-built binary failing on
Debian. The runtime image installs ffmpeg, qalc, the shared libraries, and
the latest yt-dlp zipapp, and runs as uid 1000.

compose.yaml mounts data/ and piper/, overrides TTS_MODEL_PATH for the
container layout, and builds with host networking because the default
Docker bridge DNS cannot resolve crates.io or deb.debian.org on this host.
