Release v4.0.0-rc3: Production deployment fixes and cross-platform compatibility

- Fix production build path resolution for CSS/JS/images
- Resolve sidebar navigation layout issues (badges, arrows, spacing)
- Fix RTL CSS processing interference with LTR builds
- Update dependencies (Bootstrap 5.3.7, Bootstrap Icons 1.13.1, OverlayScrollbars 2.11.0)
- Remove CDN integrity attributes to prevent digest mismatches
- Add dist/ to .gitignore to exclude build files from repository
- Implement smart relative path calculation for all deployment scenarios
- Add runtime image path correction for sub-folder deployments
- Ensure development and production environment parity
- Fix all ESLint compliance issues (prefer-global-this, prefer-string-slice)

Major improvements:
✅ Production builds now work identically to development
✅ Images, CSS, and JavaScript load correctly in any deployment structure
✅ Sidebar displays properly with badges and arrow indicators
✅ Zero console errors from CDN resources
✅ Full compatibility with FTP/static hosting platforms
