[Feature Request]: Toggle to strip "music." from shared links

Preflight Checklist

• I use the latest version of Pear Desktop (Application).
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem Description

The Share panel currently generates music.youtube.com URLs. Using canonical youtube.com links would make shared songs more recognizable and consistent with standard YouTube URLs, since music.youtube.com is not generally expected when sharing YouTube content.

Proposed Solution

Add a new Settings option, "Strip 'music.' from shared links" (default: off). When enabled, URLs copied or displayed by YouTube Music should use the canonical youtube.com format instead of music.youtube.com. This should apply to the Share panel and the Navigation > Copy current URL menu action. The change should be cosmetic only: the app origin, CORS behavior, and internal API endpoints should remain unchanged.

Alternatives Considered

Provide this as an optional plugin (non-default) that rewrites the share panel/clipboard; expose a per-user setting in Options to enable it; or allow users to specify a custom share URL format in advanced settings.
