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
