Add native Web Share API for photo sharing

- Install react-share library and add native sharing to ImageModal
- Replace Facebook-specific sharing with Web Share API for broader compatibility
- Extract GPS location from EXIF data for enhanced share text
- Support file sharing with fallbacks to URL/clipboard for unsupported devices
- Add smart share text generation with location coordinates and camera info
- Perfect for private hosts - shares actual files without external URLs
- Update CLAUDE.md with completed roadmap items and coding standards

-- I'll run dev myself
+# Claude Instructions
+- Never automatically change or add files without user confirmation
+- Never try to run the dev server, user will always manually run dev
+- Run builds automatically to check for errors
+
+# Code Standards
+- Files over 300 lines should be split into multiple files
+- Use functional components with hooks
+- Use Tailwind CSS for all styling, no custom CSS unless absolutely necessary
+- Use next/image for all images
+- Use next/font for all fonts
+- Write clear, concise, and well-documented code
+- Double check approach against current frameworks and libraries
+- Always ask for user confirmation before making large changes
+
+# Audit
+- When asked if there are libraries to accomblish custom functionality, check npm 
+- When asked for alternatives give multiple options with pros and cons
