Library and CLI tool for 3D Gaussian splat format conversion and transformation

/**
 * WGSL source for the project compute. Reads raw splat fields from the
 * per-slot input buffer, evaluates SH for view-dependent color, computes
 * 2D inverse covariance + screen-space 3σ radius, and writes a packed
 * projection record per gaussian. Invalid splats (behind near, degenerate
 * covariance, outside group AABB) are written with `radius = 0` so the
 * rasterizer can early-out on the first vec4 load.
 *
 * Projection-mode variation (pinhole vs equirect) is handled at WGSL
 * preprocessor time via `#ifdef PROJECTION_EQUIRECT` blocks that pull
 * in the projection-specific chunks (screen mapping + Jacobian + tile
 * AABB). The per-render `MAX_COVERAGE_PER_SPLAT` cap is similarly
 * embedded by the tile-AABB chunk via JS-template substitution at
 * construction time (see `sharedCincludes` in the rasterizer ctor).
 *
 * @param coeffsPerChannel - Per-channel SH coefficient count (0/3/8/15).
 * @returns WGSL source for the project compute shader.
