[CharlVS]

This PR rolls the KDF API to commit 4c4df1326bcad6aa25ab837cad4fc84147e15084 on staging and updates the platform artifact checksums for web, iOS, macOS, Windows, Android (armv7, aarch64), and Linux.

• Update api_commit_hash to 4c4df13
• Refresh valid_zip_sha256_checksums per platform

Please run CI to publish new artifacts as needed.

Keep checksums for all matching artifacts

The config still allows downloading both kdf_* and mm2_* archives (see the matching_pattern), but each platform’s valid_zip_sha256_checksums list now contains only a single hash. The download helper chooses the first asset matching the regex without preferring kdf over mm2 when no matching_preference is provided (update_api_config.dart::_fetchGithubDownloadUrl). If a release lists an mm2_* asset first—or only publishes the mm2_* variant—the checksum check will now reject that download and the build will fail. Keeping the second checksum (or restricting the regex to the artifact you intend to fetch) avoids breaking platforms whenever the release asset ordering changes.
