fix(linux): window drag stuck mouse bug

- Fixed critical bug where dragging custom title bar on Linux caused
  mouse to get stuck in drag mode, preventing any other interaction
- Root cause: egui's widget-level drag tracking desynchronized with
  window manager after ViewportCommand::StartDrag was sent
- Solution: bypass egui's drag state machine entirely using raw input
  detection (primary_pressed()) for immediate window drag initiation

Release v0.2.5.2:
- Updated README.md with v0.2.5.2 release notes
- Updated CHANGELOG.md with full v0.2.5.2 release details
- Updated ROADMAP.md to mark v0.2.5.2 as released
- Synced all features/fixes from ROADMAP to CHANGELOG

+### Added
+
+#### New Features
+- **Delete Line shortcut** ([#29](https://github.com/OlaProeis/Ferrite/pull/29)) - Cmd/Ctrl+D deletes current line (configurable in settings) - thanks [@abcd-ca](https://github.com/abcd-ca)!
+- **Move Line Up/Down** ([#29](https://github.com/OlaProeis/Ferrite/pull/29)) - Alt+Up/Down swaps current line with adjacent line - thanks [@abcd-ca](https://github.com/abcd-ca)!
+- **macOS file type associations** ([#30](https://github.com/OlaProeis/Ferrite/pull/30)) - Ferrite appears in Finder's "Open With" menu for .md, .json, .yaml, .toml, .txt files - thanks [@abcd-ca](https://github.com/abcd-ca)!
+
+#### Internationalization
+- **I18n audit & cleanup** - Comprehensive audit of hardcoded strings, replacement with translation keys
+- **Orphaned key removal** - Removed ~200 unused translation keys from locale files
+- **Locale file sync** - All locale files now have consistent structure matching en.yaml
+- **New language support** - Added Estonian and Norwegian Bokmål via Weblate community translations
+
 ### Fixed
 
+#### Bug Fixes
 - **Ctrl+X cutting entire document** - Fixed egui bug where Ctrl+X with no text selection would cut the entire document. Now correctly does nothing when nothing is selected.
+- **Linux window drag stuck mouse** - Fixed critical bug where dragging the custom title bar on Linux caused the mouse to get "stuck" in drag mode. Root cause: egui's widget-level drag tracking desynchronized with the window manager after `ViewportCommand::StartDrag`. Fix bypasses egui's drag state machine entirely, using raw input detection (`primary_pressed()`) for immediate, reliable window drag initiation.
+- **Split mode cursor position** ([#29](https://github.com/OlaProeis/Ferrite/pull/29)) - Line operations now work correctly in Split view; rendered pane no longer overwrites cursor position - thanks [@abcd-ca](https://github.com/abcd-ca)!
+- **macOS modifier tooltips** ([#28](https://github.com/OlaProeis/Ferrite/pull/28), [#29](https://github.com/OlaProeis/Ferrite/pull/29)) - Tooltips now show "Cmd+E" on macOS instead of hardcoded "Ctrl+E" - thanks [@abcd-ca](https://github.com/abcd-ca)!
+- **Semantic minimap highlight accuracy** - Use byte offsets matching search behavior for correct highlight positioning
+
+> **Note:** Opening files via "Open With" or dragging onto app icon not yet supported on macOS due to [winit#1751](https://github.com/rust-windowing/winit/issues/1751). Workaround: use `open -a Ferrite file.md` or File > Open.
