2.2.2

Playback-clock correctness. The engine now presents a single source-PTS timeline. No breaking API change, existing 2.2.x callers are unaffected.

Changes

• Unified the playback clock onto source PTS. On the native HLS path currentTime previously mirrored AVPlayer's loopback clock (source_pts - playlistShiftSeconds) while sourceTime carried source PTS, forcing every source-timeline consumer (subtitle scheduling, media-segment intro/outro detection, resume reporting) to pick the right one of two clocks. The shift is now folded into the published currentTime, so currentTime == sourceTime on every path (the software and audio paths already ran on source time). Resume and reloadAtCurrentPosition get slightly more accurate as a result, and on a rare imprecise restart seek the reported position now reflects the true landed frame.
• seek(to:) is now source-PTS based and converts to the loopback clock internally (a no-op on the software and audio paths, where the shift is 0). A seek(toSourceTime:) alias exists but is deprecated, since seek(to:) now covers it. sourceTime stays public as a stable alias for callers that want to express source-timeline intent explicitly.
