- Build script (scripts/build.mjs) using esbuild with iterative stub creation - Stubs for Bun compile-time intrinsics (feature(), MACRO, bun:bundle) - Stub modules for feature-gated internal code paths - QUICKSTART.md with 3 build options (pre-built, esbuild, Bun) - tsconfig.json, package.json for build tooling Build reaches ~95% — 108 remaining feature-gated modules need Bun runtime for full dead code elimination. See QUICKSTART.md for details. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

|
* prepare-src.mjs — Pre-build source transformation
|
|
*
|
|
* This script patches the source tree to make it compilable without Bun:
|
|
* 1. Replace `import { feature } from 'bun:bundle'` with our stub
|
|
* 2. Replace `MACRO.X` references with runtime values
|
|
* 3. Create missing type declarations
