📝 WalkthroughWalkthroughPlayback metadata now includes recap and preview ranges. Android and TV playback state propagate these ranges from watch details and realtime updates to player controls. Mobile and TV progress indicators render distinct marker bands for intro, recap, credits, and preview. ChangesPlayback marker propagation

189-194: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the marker-color mapping into a shared constant. Both platforms hard-code the identical intro/recap/credits/preview color mapping independently. The shared root cause is the absence of one marker-color definition in a common module.

Resolves the TvPlayerIdleOverlay signature conflict with Silo-Server#224's timeline markers: keep main's creditsRange/recapRange/previewRange, and keep this branch's removal of isBuffering/sleepTimerState from the idle overlay (both moved to TvPlayerOverlays so the capsule survives hidden controls).

What
The player timeline now renders all four server-detected marker types instead of just the intro. Previously the client decoded and displayed only the intro band, and even credits were ignored on the timeline, while the server was already sending four kinds: intro, credits, recap, and preview.
Each marker now gets its own tinted band on the scrubber, on both phone and TV:
Why
The Silo server has supported recap and preview markers for a while, but the Android clients were dropping them. The realtime
markers_updateddecoder only read theintroandcreditskeys, and even credits were never drawn on the timeline (they were used only to trigger the "Up Next" auto-advance). So two of the four marker kinds the server identifies simply never reached the UI.This closes that gap by threading recap and preview through the same pipeline intro/credits already use, and drawing all four as distinct bands.
Changes
