• Firefox: saving site settings failed with Lost the connection to the extension — Firefox structured-clones port messages and rejected the Svelte reactive proxy. The draft is now snapshotted to a plain object before posting.
• Fixed two pre-existing type errors in the settings panel (double-cast through unknown); svelte-check and tsc now pass clean.

Full Changelog: https://github.com/Lebenoa/Enoact-Browser-Extensions/compare/v2.0.0...v2.0.1

A major rework: Twitch support, a full settings sidebar, and presence that stays
accurate in background tabs. Recommended for all users on v0.1.0.

• Twitch presence — live stream title, channel name/avatar, and preview
  thumbnail, with per-site settings like the other sites.
• Settings sidebar — a settings UI built into the extension; every setting is
  per-site and applies to already-open tabs immediately (no reload needed).
• Reliable background presence — playback time and pause state are read from
  the live <video> element, so progress no longer freezes while you work in
  another tab.
• Efficient updates — updates are JSON-diffed and pushed only on change, with
  event-based extraction as the new default (polling remains available and its
  interval is configurable).

• Twitch presence support (title, channel, avatar, thumbnail)
• Settings sidebar with per-site enabled toggles and options
• Settings changes apply to already-open tabs via config broadcast
• Presence updates sent only when the activity payload changes, and re-sent
  after reconnecting
• Event-based extraction mode: pushes on play/pause/seek/track change and
  idles otherwise; now the default for fresh installs (stored installs keep
  their choice)
• Configurable presence update interval per site (default 5s, 1–60s clamp);
  only meaningful in polling mode
• Configurable status display type (Details vs State) with sane per-site
  defaults (YouTube/YouTube Music: Details; Twitch: State)
• Restyled settings panel around the Enoact mark (gradient signal rail,
  notched corners, toggle switches) + site favicons in the site list

• Read playback time/pause state from the live <video> element — player API
  getters go stale in unfocused tabs and froze the progress bar
• YouTube Music: song thumbnails restored (wrong microformat key + shim omitted
  videoDetails.thumbnail)
• Twitch: show the streamer's display name, not the lower-case URL slug
• Twitch: use the streamer's avatar, not a followed-channels sidebar avatar
• YouTube: channel avatar read from component data — the rendered <img> is
  lazy-loaded and has no src in background tabs
• Playback/config/shutdown edge cases: inverted paused predicate on YouTube
  Music before the video element exists, stale MAIN-world shim data after SPA
  navigation, re-enabling a site now reaches tabs loaded while it was disabled,
  dev.ts no longer orphans children that ignore SIGTERM, and the sidebar
  re-requests settings after the worker wakes up
