5.0.1

Patch release. Five fixes on top of 5.0.0, no API changes.

Fixed

• Split MPEG-TS PGS display sets reassemble before decode (#112). On Blu-ray MPEG-TS a PGS display set spans several PES packets (PCS, WDS, PDS, ODS, END). The packet-tap store kept one entry per harvested packet keyed by unique PTS, so segments without a PTS died at the NOPTS guard and segments sharing one collapsed in the same-PTS replace; the decoder never saw the palette and object definitions and every set failed at its END segment ("Invalid palette id"). The store now reassembles armed streams' chunks into one self-contained entry at the PCS presentation PTS. Arming comes from the demuxer (PGS streams in an mpegts container) through both hosts' tap sinks; Matroska stays on the per-packet path.
• iOS route-sharing policy no longer blocks host PiP (#116). The shared AVAudioSession declared .longFormAudio on every platform. On iOS that marks the process a long-form audio client, which pins AVPictureInPictureController.isPictureInPicturePossible to false for any host-built PiP controller around the engine's player layer. The policy is now platform-split: tvOS keeps .longFormAudio (HDMI route negotiation), iOS declares .default.
• Dolby Vision first frame no longer waits out a fixed 5 s poll (#117). waitForSwitch() polled isDisplayModeSwitchInProgress for a fixed 5 s and never watched the OS mode-switch notifications, so on panels where a DV switch is unobservable to the app it ran the full timeout every time, and load() waits twice, roughly 10 s to first frame. It now settles the instant the panel reports done (AVDisplayManagerModeSwitchStart / End, or EDR headroom rising) and otherwise caps the wait at ~2 s. Observable panels settle immediately; SDR and rate-only loads are unaffected.
• LoadOptions.httpHeaders reaches the nativeRemoteHLS path (#119). The remote-HLS bypass built its AVURLAsset without an options dictionary, silently dropping the headers, so header-enforcing IPTV origins (per-stream Referer / User-Agent / Authorization) answered 403 and those channels could not play at all. The headers now ride the asset via AVURLAssetHTTPHeaderFieldsKey, and the remote-HLS audio tap fetcher (#95) sends the same headers on its own playlist, segment, and AES-key requests.
• Pre-bound surfaces show video on loadRemoteHLS (#120). The lean remote-HLS bypass assigned its host and early-returned without presenting the player layer, so a surface bound before load (the usual SwiftUI order: view appears, then the load task fires) never attached playerLayer and every remote-HLS live channel played audio over black video. The layer is now presented right after the host is assigned, mirroring loadNative.
