Pulsar Lighting Engine

Fixed

• Fixed large vanilla and JSON Paintings canvases rendering with abrupt, block-sized lighting bands. When smooth lighting is enabled, paintings now interpolate light across tile boundaries (MC-1531, #5).
• Fixed dense skylight edits, such as large roofs and leaf canopies, leaving stale light behind or reintroducing light across chunk borders (MC-117067, MC-117094). Dense batches now rebuild only the skylight lane, preserving simultaneous block-light updates.
• Fixed block light failing to enter or clear from block-empty sections across chunk borders (MC-116690).
• Fixed full chunk packets omitting block-empty sections that still contain non-default sky or block light (MC-80966).
• Fixed vanilla and Forge liquids not using neighbouring brightness values (MC-104532).
• Fixed the level-one emitter case of MC-50734, and fixed self-shadowing on stronger emitters (MC-249343).

Changed

• Refactored the lighting pipeline and chunk mixins into smaller, responsibility-focused components to improve maintainability without intended behavior changes.
