2.3.0

New public API for media metadata, plus episode-autoplay playback-reliability fixes. No breaking API change, existing 2.x callers are unaffected.

Changes

• MediaMetadata extracted on every load. The demuxer parses normalized container tags (title, artist, album, albumArtist, with whitespace cleanup) and pulls embedded cover art. The engine publishes it at load time and exposes it through SourceProbe, and aetherctl prints the parsed container metadata in its probe output. Driven by the AetherPlayer media-player work.
• Episode autoplay no longer starts audio before video. The native AVPlayer reused across native-to-native reloads (since 2.2.1) carried its previous rate=1.0 into the next item, so the new episode auto-resumed before the display-criteria handshake and played audio while the panel was still mid Match-Frame-Rate switch. The host now pauses the player across the item swap, so the post-handshake play() gates the start.
• No more mid-playback stall plus A/V desync a minute or two into a stream. SegmentCache evicted already-produced forward segments when AVPlayer did a transient backward refetch (an audio handover or decode flush moved the prune target back), which forced a cache-miss producer restart that re-muxed from a fresh init segment. The forward prune bound is now anchored on the highest stored index so produced-but-unconsumed segments survive the dip, and the restart decision no longer treats a resident segment the producer merely raced past as a pruned gap.
