Phase 1 of the player panels redesign:
- New PanelSettings model (pages, regions, layout mode, default
visibility) stored as an optional field on PlayerControlsLayout with
an effectivePanelSettings accessor; lenient Codable so future page
types and settings payloads never corrupt saved presets.
- New Views/Player/Panels content engine: PlayerPanelContentView
renders a page bar plus the selected page (info, comments, related,
chapters, queue, tracks), with runtime hiding of empty pages.
- PortraitDetailsPanel and FloatingDetailsPanel now host the shared
content instead of their duplicated info bodies; drag machinery,
pills, and fades are untouched.
- Comments list extracted into CommentsListContent shared by the
overlay and the comments page; comments pill routes to the comments
page (expanding the portrait panel) when the page is enabled, and
falls back to the overlay when it is not.
- Tracks page embeds QualitySelectorView via a new isEmbedded mode.
- Deleted the unused video info bodies in ExpandedPlayerSheet+VideoInfo
and the dead PlayerInfoTab model.
Remove the gear toolbar button that opened Settings as a sheet in the
NavigationSplitView sidebar column, and drop the macOS guard hiding
.settings from SidebarMainItem so it can be added to the sidebar and
rendered in the detail column like other items. The dedicated Settings
window (Cmd+,) is unchanged.
Exposes ContinueWatchingView as an opt-in compact tab bar item,
hidden by default. Uses a short "Continue" label since the full
"Continue Watching" string does not fit as a tab bar title.
After disabling home shortcuts on tvOS, Open URL and Remote Control had
no entry point. Add them as configurable sidebar main items. Remote
Control defaults to visible on tvOS; Open URL defaults to hidden on all
platforms.
