Pulsar Lighting Engine

Changed

• Updated the build toolchain to Gradle 9.7.1, Shadow 9.6.1, Unimined 1.4.37-kappa, JUnit 6.1.3, and actions/setup-java v6. Release workflows now use the checked-in Gradle wrapper instead of selecting a separate Gradle version.
• Added Pulsar's issue tracker URL to the generated mod metadata.

Fixed

• Fixed a crash with JSON Paintings 1.5.0 after its renderer method signature changed. Pulsar now targets both the legacy renderer and the 1.5.0 MCP/SRG variants while preserving smooth per-vertex painting lighting (#9).
