Additive, backward-compatible enhancements to the shared cast crate (the
Tauri shims are pure re-exports, so existing callers are unaffected).
- DLNA timeouts: pause/stop/seek/set_volume now run through a shared
run_action() with a 10s timeout (was none) so a hung renderer can't block
the caller forever. New DlnaError::Timeout / CastError::Timeout variants.
- DLNA mute: add set_mute / get_mute (RenderingControl SetMute/GetMute,
Master channel) — was missing alongside set_volume.
- DLNA capability detection is now version-agnostic (matches AVTransport:2/:3,
not only :1) so newer renderers report has_av_transport correctly.
- Media server endpoint auth: served path is now /audio/<token>/<id> with a
128-bit per-session token (RandomState-seeded, no new dep). Token lives in
the PATH, not a query string, so DLNA renderers that strip queries still
authenticate. Mismatch -> 403.
- register_file content-type parity: content_type_for_path now mirrors the
rich local-cast MIME map (audio/x-ape, mp3/ogg/opus/aac, m4a/alac->audio/mp4)
instead of the poorer table; add register_file_with_content_type so the
caller can supply an exact MIME. Local files stream from disk (no full-RAM
read) per decision D4.
Unit-tested: tokened-path parsing, rich MIME map, token randomness.
