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

/**
 * Format a JS number as a WGSL `f32` literal. Adds an explicit `.0` so
 * integer-valued constants like `3` aren't parsed as `AbstractInt` —
 * keeps shaders readable when the constant flips to a fractional value.
 *
 * @param n - Numeric value to format.
 * @returns WGSL literal string with explicit `.0` for integer values.

/**
 * Shared render-time tunables declared as WGSL `const` so every shader can
 * reference them as plain identifiers. Bound to the JS-side values in
 * [render/config.ts](../../render/config.ts) — the single source of truth.
 *
 * The PlayCanvas WGSL preprocessor's `cdefines` mechanism only registers
 * symbols for `#ifdef` checks; it does not substitute bare identifiers
 * with their values. WGSL `const` declarations cover that gap and can
 * additionally be used inside `@workgroup_size(...)` and other const-
 * expression contexts.
 *
 * Included via `#include "constants"` (see `sharedCincludes` in
 * `gpu-splat-rasterizer.ts`).
