v0.4.1 — Service Worker Persistence, Ability Test Harness

What's New

Service Worker Persistence Fixed

• Added sw-loader.php to serve the Service Worker with the Service-Worker-Allowed: /wp-admin/ header — the SW now registers correctly and the model persists across page navigations (no re-download needed)
• Moved sw-loader.php to plugin root so wp-scripts build can't accidentally delete it
• Synced SW version format with plugin version (0.4.101) for predictable cache busting

Ability Test Harness (WebLLM)

• Rebuilt the ability test harness for WebLLM (previously lost transformers.js prototype)
• Headless Chrome + WebGPU via Puppeteer — runs Qwen 3 1.7B, executes ReAct agent against test cases
• 8/8 tests passing: tool selection (6/6) + no-tool knowledge questions (2/2)
• Run with: npm run test:abilities -- --file tests/abilities/core-abilities.test.js
• Third-party developers can test their own abilities using the same harness

Repo Cleanup

• build-extensions/ removed from git tracking (generated on build/distribution only)
• build-test-harness/ gitignored (dev-only artifact)

Documentation

• Added IDEAS.md section #10: transformers.js / ONNX Runtime experiment findings
  • What works (0.5B on WebGPU, SW persistence with WASM)
  • What doesn't (1.5B+ hits ORT WASM memory limits)
  • Investigation leads for hackathon
