[BUG] Playwright grabengine (tvtv.ca/tvtv.us) fails to launch on Alpine — glibc/musl incompatibility not resolvable even with workarounds

linuxserver/webgrabplus イメージを使用して失敗を再現し、/config/WebGrab++.log.txt にあるコンテナログを調査します。まずイメージの Dockerfile と Playwright ドライバーのパス /config/.playwright/node/linux-x64/node を確認し、現在の Alpine ベースのイメージでの起動失敗に焦点を当てます。tv tv.ca.ini または tvtv.us.ini grabengine がヘッドレスブラウザーを起動して EPG データを取得できれば完了です。

Is there an existing issue for this?

Current Behavior

Site configs that use WebGrab+Plus's playwright.browser.* grabengine (e.g.
tvtv.ca.ini, tvtv.us.ini) fail to launch on the current Alpine-based image:
[Error] Failed to create Playwright: [Error] An error occurred trying to start process '/config/.playwright/node/linux-x64/node' with working directory '/app/wg++/bin.net'. No such file or directory

Expected Behavior

being able to use playwright for channels that need it.

Steps To Reproduce

5. Check /config/WebGrab++.log.txt inside the container

Expected: WebGrab+Plus launches a headless browser (Chromium/Firefox, via
Playwright) and grabs EPG data from the tvtv.ca/tvtv.us channel(s).

Actual: on first use, WebGrab+Plus downloads the Playwright driver
successfully, then fails immediately when trying to launch it:
