Description

Summary
This PR moves the hardcoded wire-gradle-plugin dependency from the root build script to the central Version Catalog (libs.versions.toml).

Technical Details

• Added wire-gradle-plugin version and library entry to gradle/libs.versions.toml.
• Updated the root build.gradle.kts to reference the catalog alias instead of a hardcoded string.
• Maintained the necessary exclude rules for the Wire plugin by resolving the catalog entry to its string representation.

Verification

• Verified the build environment starts correctly by running ./gradlew help.
• Confirmed the fix addresses the "Hardcoded Dependencies Found" warning in the Lighthouse report.
