Ether 0.2.52

This release fixes pre-play audio and subtitle track selectors across cold
detail-page opens, stopped playback, and TV show/season views on Plex clients
(including NVIDIA Shield / Android TV), fixes embedded text subtitle playback
during remux/transcode sessions, and adds default TRaSH release group custom
formats to quality profile imports.

Plex Playback and Pre-Play Track Selectors

• Synchronous detail-page warm-up probe (WaitWarmProbe): opening a movie
  or episode detail page now waits up to a bounded budget (4s) for the
  background warm probe (probeGeneration) to complete before rendering
  <Media><Part><Stream> metadata, so the very first detail-page visit lists
  real embedded audio and subtitle tracks instead of a single estimated track
  (#145).
• Retain probed tracks on Auto across fallback candidates and playback:
  when Auto playback selects a candidate other than Variants[0] (because
  the top cached search result was skipped during health or debrid cache
  checks), stopping playback and returning to the detail page now attaches the
  probed tracks to the Auto entry (Media[0]) instead of dropping all
  <Stream> tags (#145).
• Retain warm-probed tracks across Prepare and extended browsing:
  consuming a warm resolution for playback now preserves its probed MediaInfo
  in the warm cache (60m TTL, 128 entries, 30/min detail warm-up budget,
  and automatic replacement of stale in-flight detail warm-ups when navigating
  to a new title), and ResumedTracks matches across LAN/WAN remote-cap
  boundaries in Docker bridge setups (#145).
• TV show OnDeck and season episode track warming: opening a TV show page
  (includeOnDeck=1), /ondeck, or a season episode list (/children) now
  warms the next playable episode (OnDeck or first unwatched/in-progress
  episode) and includes its probed <Stream> tags in the response (#145).
• Embedded text subtitles during remux and transcode sessions: selected
  non-burned embedded text subtitles in remux/transcode decisions now report
  location="sidecar" with key="/library/streams/<id>" and serve extracted
  WebVTT/SRT cues from /library/streams/<id> and
  /video/:/transcode/universal/subtitles, instead of reporting
  location="segments-subtitle" when FFmpeg runs with -sn (#145).

Quality Profiles and Import

• TRaSH default release group custom formats: quality profile imports now
  include built-in TRaSH release group custom formats (WEB Tier 01/02/03,
  HD Bluray Tier 01/02/03, UHD Bluray Tier 01/02/03, Remux Tier 01/02,
  LQ, LQ (Release Title), Bad Dual Groups, No-RlsGroup, Obfuscated,
  Retags, Scene) with pre-populated regex rules so imported profiles score
  release groups out of the box (#86, #172 — thanks @evulhotdog!).
