Release 0.1: Complete BinectChrome implementation

Implements all requirements from ProductRequirementsDocument.md:
- PDF detection via Chrome Downloads API
- Secure credential storage with AES-GCM encryption
- Binect API integration for PDF uploads
- Popup UI with Binect branding
- Local transfer tracking (500 entry cap)
- Help page with tracking view and CSV export
- 60-day credential retention with auto-expiry
- Accessibility compliance (WCAG 2.1 AA)

Technical implementation:
- Chrome Extension Manifest V3
- TypeScript with strict mode
- Webpack build system
- Jest test suite (22/22 passing)
- ESLint configured (0 errors)

Build output: 13 KB total (production minified)
Test coverage: crypto, pdf-detector, tracker, binect-api
