v4.0.4

[niklasramo]

4.0.4

No API Changes

The library source code (src/index.ts) is unchanged. This is a maintenance release focused on project structure, tooling, and documentation.

---

✨ New

• Sourcemaps now included — index.js.map and index.cjs.map are now shipped for better debugging

📦 Project Restructuring

• Tests moved to separate package — tests/ is now a standalone package with its own package.json, reducing root devDependencies
• Switched bundler from tsup to tsdown — smaller, faster builds
• Added Prettier config to benchmarks — consistent formatting across all packages

📝 Documentation

• New "Tips and tricks" recipes:
  • Scheduled callback with deduplication (debounce / coalesce) — using stable IDs with once() for debounce patterns
  • Hot-swap a listener without changing its position — using dedupe: 'update' for stable slots
• Fixed typos in API examples
• Updated CDN URL to use major version (@4) instead of pinned patch version
• Updated bundle size — 561 → 568 bytes (the sourcemap url added a bit of extra weight)

🛠 Tooling & Scripts

• Added sideEffects: false to package.json for better tree-shaking
• Added convenience scripts: setup, setup-clean, bump-deps
• Alphabetized and reorganized npm scripts
