refactor(qconnect): extract remote track streaming and load dedup to track_loading.rs
Move 7 items that own remote track loading (HTTP streaming, FLAC probe,
fallback download, and the load-attempt dedup window) into a dedicated
track_loading submodule:
- LOAD_ATTEMPT_DEDUP_WINDOW (5s constant)
- should_reload_remote_track (track-id-only reload predicate)
- load_remote_track_into_player (top-level load with streaming-then-
download fallback)
- is_recent_load_attempt (dedup check against sync_state)
- ensure_remote_track_loaded (pub(super) — orchestrator called by
corebridge::apply_renderer_command_to_corebridge and the V2
play_track_handoff path)
- QconnectRemoteStreamInfo (FLAC probe result)
- stream_remote_track_into_player, probe_remote_stream_info,
download_and_stream_remote_track, download_remote_audio
corebridge.rs now imports ensure_remote_track_loaded directly from
super::track_loading instead of going through mod.rs.
Pure relocation. mod.rs: 4777 → 4460 lines. track_loading.rs: 337 lines.
Total qconnect/ submodules now: 6 (types, session, queue_resolution,
corebridge, track_loading, plus the residual mod.rs).
