chore: added remaining tasks for NPM publication to TODO

Phase 6 Complete:
- ✅ Created test/umd-test.html (UMD bundle verification)
- ✅ Created test/minified-test.html (production build test)
- ✅ Created test/esm-test.html (ES Module format test)

Each test file demonstrates:
- Bundle loading and initialization
- marked.js peer dependency integration
- Control panels and event system
- Complete feature showcase
- Usage examples and code snippets

Tests verify all build outputs work correctly in browsers.
Open any test/*.html file in a browser to verify functionality.

+# Todofile
+
+This is a "to do next" file, particularly useful to keep the human and a coding assistant in sync.
+
+The format is based on [Keep a Todofile V0.0.1](https://coulomb.social/open/KeepaTodofile).
+
+The structure organizes **future tasks** by their impact, just as a changelog organizes past changes by their impact.
+
+***
+
+## [Unreleased] - *Active Vibe-Coding State* 💡
+
+This section is for tasks currently being discussed with or worked on by the coding assistant. These are the ephemeral, flow-of-thought tasks.
+
+### NPM Publication - Remaining Tasks
+
+**Status**: Phases 1-6 complete ✅ (build system, bundling, testing)
+**Remaining**: Phases 7-9 (pre-publication, publication, post-publication)
+
+#### Phase 7: Pre-Publication Setup
+- [ ] Run `npm pack` to create package tarball
+- [ ] Test packed version locally (`npm install ./testdrive-jsui-1.0.0.tgz`)
+- [ ] Setup npm account (`npm login` or create account)
+- [ ] Decide repository structure (separate repo vs monorepo)
+- [ ] Create git tag: `git tag -a v1.0.0 -m "Release v1.0.0"`
+- [ ] Run final pre-publish checks:
+  - `npm run lint` (no errors)
+  - `npm test` (all tests pass)
+  - `npm run build:prod` (clean build)
+  - `npm publish --dry-run` (verify what will be published)
+
+#### Phase 8: Publication
+- [ ] Publish to npm: `npm publish`
+- [ ] Verify package on npmjs.com
+- [ ] Wait 5-10 minutes, then verify CDN availability:
+  - jsdelivr: `https://cdn.jsdelivr.net/npm/testdrive-jsui@1.0.0/dist/testdrive-jsui.min.js`
+  - unpkg: `https://unpkg.com/testdrive-jsui@1.0.0/dist/testdrive-jsui.min.js`
+- [ ] Create GitHub release from v1.0.0 tag
+- [ ] Test fresh install: `npm install testdrive-jsui marked`
+
+#### Phase 9: Post-Publication
+- [ ] Add npm badges to README.md
+- [ ] Create live demo page (optional)
+- [ ] Setup GitHub Pages for demo (optional)
+- [ ] Create announcements (optional)
+- [ ] Monitor downloads and feedback
+
+### Other Tasks
+- [ ] Make sure that Markitect integration still works fine
+- [ ] Update STANDALONE_PLAN.md and decide if it should be implemented
+

+## What is ESM?
+
+**ES Modules** (ECMAScript Modules) use modern JavaScript \`import\` and \`export\` syntax.
+
+### Features:
+- ✅ Native browser support (no bundler required)
+- ✅ Tree-shaking friendly
+- ✅ Async loading by default
+- ✅ Better for modern build tools
+
+### This Build:
+- **File:** \`dist/testdrive-jsui.esm.js\`
+- **Size:** 199KB
+- **Format:** Pure ES6 modules
+- **Target:** Modern browsers & bundlers
+
+## Usage in Modern Apps
+
+### With Vite
+\`\`\`javascript
+import TestDriveJSUI from 'testdrive-jsui';
+import 'testdrive-jsui/dist/testdrive-jsui.css';
+
+const editor = new TestDriveJSUI({
+  container: '#app',
+  markdown: '# My App'
+});
+\`\`\`
+
+### With Webpack 5
+\`\`\`javascript
+import TestDriveJSUI from 'testdrive-jsui';
+// CSS handled by css-loader
+import 'testdrive-jsui/dist/testdrive-jsui.css';
+\`\`\`
+
+### With Rollup
+\`\`\`javascript
+import TestDriveJSUI from 'testdrive-jsui';
+// Rollup will tree-shake unused code
+\`\`\`
+
+## Benefits
+
+1. **Tree Shaking**: Bundlers can remove unused code
+2. **Code Splitting**: Modern bundlers can split this module
+3. **Native Browser Support**: Works directly in modern browsers
+4. **Better DX**: Cleaner import syntax
+
+---
+
+**Perfect for modern JavaScript applications! 🎯**`,
