Pulsar Lighting Engine

Changed

• Update CleanroomDevEnv to 6b24e5c, with Kotlin DSL build scripts and parallel configuration caching. Native compatibility tests support configuration caching; the standalone API publication and production JAR checks remain available.
• Apply version tokens to all compiled classes and check class constant pools for unresolved tokens, avoiding false matches in binary data.
• Select JVM runtime variants when resolving embedded dependencies.
• Move Spotless profiles to gradle/spotless and extend Renovate dependency coverage.
• Validate release-note extraction and retain support for resuming interrupted uploads. GitHub Releases continue to use the pre-release flag disabled.
• Add LGPL-3.0-only source headers while preserving upstream copyright notices and the CleanroomDevEnv MIT notice. The API publication declares its LGPL license.

Removed

• Remove Actinium-specific renderer integration. Actinium targets Cleanroom 0.6.x; Pulsar requires Cleanroom 0.7.14-alpha or newer within the 0.7.x series.
• Remove Felt build tooling and its header-management configuration.

Fixed

• Respect closed outgoing block faces during SCALAR and RGB light recalculation, avoiding false mismatches and unnecessary relighting at chunk boundaries near slabs and other sided blocks.
• Release completed tasks and their chunk references from stale priority indexes when a lighting queue drains.
• Clear partially initialized engine caches after setup failures, so reused engines do not retain stale chunk data.
• Reject invalid saved light-nibble states on load, allowing corrupt caches to relight before they can cause errors on later saves.
