feat: Full build successful + Spotify premium patch structure

Adds an opt-in patch that forces the local Restrictions.disallowSkippingNextReasons()
getter (read by every skip button in the app) to always report an empty
set, and forces the rapid-skip cooldown tracker to always behave like it
does after the first-ever skip. This removes the free-tier "6 skips per
hour" cap and its toasts, and as a side effect also unlocks the skip
button while an ad is playing, since it reads the same restriction.

This is purely a client-side behavior change: it does not report a
Premium account to Spotify's backend, and does not block or mute ad
audio itself.

Verified against a real Spotify 9.1.78.2215 APK via revanced-cli: both
fingerprints resolve and the patch applies cleanly.
