fix: make version control info empty for reproducible F-Droid builds

* fix: disable versionControlInfo for reproducible F-Droid builds

Add versionControlInfoEnabled = false to strip the embedded git
revision metadata from the APK. This prevents byte-level differences
between GitHub-released and F-Droid-built APKs (AGP embeds branch
name, which differs between detached-HEAD CI and main-branch builds).

* fix: make version control info empty for reproducible F-Droid builds

The extractReleaseVersionControlInfo task generates
META-INF/version-control-info.textproto, which differs between
GitHub CI (builds on main branch) and F-Droid CI (detached HEAD).
This caused a 'dex/prof differs from embedded git revision' failure.

Fix: empty the file via doLast hook + exclude it from packaging.

* fix: use robust task hook for reproducible version-control-info

Replace brittle buildFeatures flag (not available in AGP 9.0.1)
with a lazy tasks.matching hook that empties the generated
version-control-info.textproto after extraction. Both CI
environments produce identical content (empty file), ensuring
byte-for-byte reproducible APKs.
