YouTube Music adapter broken: `playerApi` replaced by async `resolvePlayerApi()`

[Skaut0071]

Extension version: 3.1.0
Browser: Opera (Chromium-based)
Site: music.youtube.com

Problem
The built-in "YouTube Music" adapter no longer detects playback. Media info never registers with external adapters (tested with Macro Deck 2), while other sites (YouTube, Jellyfin, etc.) work fine and the WNP <-> adapter connection itself is confirmed working.

Root cause
The adapter's Be() helper reads:

document.querySelector("ytmusic-player-bar")?.playerApi

This property no longer exists on the element. Checked via console:

document.querySelector("ytmusic-player-bar").playerApi
// undefined

YouTube Music appears to have replaced it with a method:

document.querySelector("ytmusic-player-bar").resolvePlayerApi()
// returns Promise<PlayerApi>, not a synchronous value

Because Be() (and therefore ready(), getCurrentTime(), etc.) is written as synchronous, the whole adapter silently fails:

window._wnp["YouTubeMusic"].ready()
// undefined

Meanwhile the actual player element still works fine:

document.querySelector("#movie_player")
// <div class="html5-video-player ...">

and navigator.mediaSession.metadata / navigator.mediaSession.playbackState are populated correctly, confirming this is purely a stale-selector issue, not a page-detection or extension-permission problem.

Happy to test a fix or provide more console output if needed.
AI helped me to find whats wrong so it could be wrong too.
