/**
 * buildInfoStore - llama.cpp build information
 *
 * Reads the build version from `build.json` — embedded at llama.cpp build time
 * with the llama.cpp build number (LLAMA_BUILD_NUMBER). Shown in the UI when
 * `showBuildVersion` is enabled.
 *
 * In dev mode (via `npm run dev`), falls back to `import.meta.env.DEV`'s truthy
 * value since the artifact is not produced.
