Release v1.0.3: Enhanced NDEF reading and UX improvements

Major Improvements:
- Implement exclusive card access with retry logic and exponential backoff
- Fix Type 4 NDEF length parsing (now correctly reads NTAG424 and similar chips)
- Add enhanced card type detection (Type 2 vs Type 4)
- Implement chunked reading for large NDEF messages
- Add proper TLV parsing for Type 2 tags

Bug Fixes:
- Fix WPF window lifecycle issue (visual tree error on reopen)
- Fix NDEF length parsing incorrectly detecting extended format
- Correct data offset for Type 4 tag reading

New Features:
- Multi-line log selection and copy to clipboard
- Context menu with Copy Selected Lines, Copy All, Select All
- Runtime version roll-forward support (.NET 8.0.x compatibility)

Technical Details:
- Type 4 tags now use correct 2-byte NLEN field per NFC Forum spec
- Removed incorrect 3-byte extended length detection
- Window now hides instead of closing for proper tray app behavior
- Connection attempts exclusive access first, falls back to shared mode
- Status timeout increased from 0ms to 1000ms for better card detection
