feat: v0.2.0 — TypeScript full rewrite, 95%+ core coverage

BREAKING CHANGE: All source files converted from JavaScript to TypeScript.
- 12 .ts source files with strict types, full EditorOptions/Plugin/Token interfaces
- 7 .ts test files, 610 total tests (27 new), 7 suites all passing
- tsc --noEmit: 0 errors
- rollup-plugin-typescript build: 5 artifacts (UMD/ESM/CJS/Min/DTS)
- @babel/preset-typescript for jest
- New tsconfig.json, updated babel/jest/rollup configs
- Coverage: parser 99.5%, utils 95.7%, themes 96.2%, core 88.8%, plugins 89.5%
- Removed types/ folder (types now inline in .ts + auto-generated .d.ts)
- Desktop-only, no backward compatibility
