Anvian's Lib

Added

• Added Config.initialize(String) for platform-resolved configuration directories.
• Added documented RegistryUtil helpers for registry values, resource keys, and tag keys.

Fixed

• Updated 26.1 resource metadata and removed references to missing mod icons.
• Telemetry now distinguishes successful HTTP responses from non-2xx responses.
