Add Adaptive Theme to System

[xLexip]

Howdy!

I'd like to suggest adding Adaptive Theme to the list. It automatically switches between Light and Dark mode using the ambient light sensor — not a fixed schedule.

Criteria Checklist

• Licensed as FOSS: GPLv3.
• Privacy: No ads, no spyware, no tracking, nothing is loaded or sent at all.
• No proprietary elements: No proprietary blobs.
• Stable: Yes.
• Actively developed: Yes.
• Free of charge: Yes.
• Source code available: https://github.com/xlexip/adaptive-theme
• Documentation: https://github.com/xLexip/Adaptive-Theme/blob/main/README.md

Transparency Note

The project is FOSS-compliant and meets all the criteria of this list. It is currently not listed on IzzyOnDroid just due to a technicality regarding the SOURCE_STAMP_V2_BLOCK (just that, no other blocks). This block is a metadata signature and does not contain any functional proprietary code or tracking. All other Izzy checks have been passed.

About SOURCE_STAMP_V2:

SourceStamp improves traceability of apps with respect to unauthorized distribution. The stamp is part of the APK that is protected by the signing block. The APK contents hash is signed using the stamp key, and is saved as part of the signing block.

It seems this is intended to ensure that all split APKs are coming from the same source, and the code to check that is public/FOSS, so we don't see why this should raise concerns – except for it being inserted by a 3rd party.

The app still meets all the requirements of this repo.
