Complete Flutter Rewrite & Feature Overhaul

EXIF Data Modifier v2.0.0

A major milestone: completely rewritten from legacy WinForms to modern Flutter Desktop (Material 3) with a frameless UI, smooth 60/120 FPS performance, and comprehensive EXIF / Geotagging tools.

---

What's New

• Complete Flutter Desktop Rewrite: Fast, portable desktop application replacing the legacy WinForms codebase.
• Modern Frameless UI: Sleek window title bar with drag-to-move, window controls, and light/dark theme support.
• Bundled Native ExifTool: Integrated standalone ExifTool engine for fast, lossless metadata writing.

Geotagging Capabilities (3 Distinct Modes)

• Manual Geotag (Geotag Tab): Quick manual coordinate assignment. Pan the map or tap to pin a location, and click Apply (automatically pins map center to selected photos if unassigned).
• Batch Geotag (Batch Geotag Tab): High-speed automated batch geotagging. Matches thousands of photos against Google Timeline JSON or GPX tracklogs with camera clock drift calibration and coordinate interpolation.
• Timeline Map & Visual Geotag (Timeline Map Tab): All-in-one visual route visualizer and geotagger. Allows you to inspect and geotag photos directly along your travel route with a photo filmstrip overlay, stay point clustering, and road snapping for maximum spatial accuracy.

Additional Core Features

• Date & Time Modifier: Batch modify DateTimeOriginal, file creation/modified dates, and apply time shifts (hours, minutes, seconds, days).
• Batch Rename: Automatically rename files using customizable timestamp patterns (e.g., IMG_yyyyMMdd_HHmmss, prefixes, counters) with restore/undo support.
• Timeline Import / Export: Import Google Location History and GPX files, merge/clean data, and export clean GPX datasets with automated backups.
• Lens & Camera Metadata: Inject camera and manual/vintage lens details (LensModel, FocalLength, MaxAperture, Make) with preset management.
