.track.toml was too generic for files that only crabidy understands;
the cbd- prefix makes them unmistakable.

A new fsdy crate exposes a configured root directory as /fs:
*.track.toml files are track nodes carrying metadata plus exactly one
playable reference — a local audio file, an http(s) URL, or a
crabidy-internal link. Link tracks rewrite Track.path to the target at
listing time, so playback routes through the existing prefix routing;
links into /fs are rejected, making chains impossible. Paths are
percent-encoded segments validated in one place (no root escape), the
orchestrator wires the provider optionally (a broken local config only
costs the /fs subtree), and the default chunked resolve walk provides
progressive queueing for free.
