fix: icon rendering, menu position, and Linux Wayland alt-tab (v0.2.5.3)

- Fix Find/Replace replace icon (↳) showing as square - use universally-supported arrow (→)
- Fix tree viewer context menu icon (⋯) showing as square - use simple dots (...)
- Add additional symbols to font atlas pre-warm list (⇄⇅↳↵…⋯)
- Fix recent files popup appearing below and covering filename - now anchored above with proper pivot
- Add app_id to ViewportBuilder for proper Wayland window management (alt-tab, taskbar)
- Update CHANGELOG.md and ROADMAP.md for v0.2.5.3

 ### Fixed
 
+#### Linux Desktop Integration
+- **Alt-tab/taskbar visibility on Wayland** - Fixed Ferrite window not appearing in alt-tab switcher or taskbar on Linux desktop environments (KDE Plasma, GNOME) running Wayland. Added `app_id` to ViewportBuilder for proper window identification.
+
+#### Icon Rendering
+- **Find/Replace replace icon** - Fixed the replace icon (↳) showing as a square box in the Find and Replace panel. Changed to a universally-supported arrow character (→).
+- **Tree viewer context menu icon** - Fixed the context menu button (⋯) in JSON/YAML/TOML tree viewer showing as a square. Changed to simple dots (...) for reliable rendering.
+- **Font atlas pre-warming** - Added additional symbols (⇄⇅↳↵…⋯) to the font atlas pre-warm list to ensure they render correctly from startup.
+
+#### UI Positioning
+- **Recent files menu position** - Fixed the recent files/folders popup menu appearing below and covering the filename button in the status bar. Menu now appears above the button using proper anchor positioning.
+
 #### Performance
 - **Linux folder opening freeze** - Fixed critical 10+ second UI freeze when opening workspace folders on Linux (especially Fedora/KDE Plasma). Root causes:
   - **notify crate misconfiguration** - Was configured with `default-features = false, features = ["macos_kqueue"]` which disabled the inotify backend on Linux, forcing fallback to slow polling-based file watching that had to walk and stat entire directory trees.

 - [x] **Git deleted file icon rendering** - Fixed git "deleted" status icon showing as a square box in file tree. Changed from unsupported Unicode character to ASCII minus.
 - [x] **Blockquote/table overflow** - Added horizontal scrolling for tables and blockquotes when content exceeds container width. Wide content no longer breaks max line width for subsequent content. Code blocks and mermaid diagrams already have internal scroll handling.
 - [x] **PowerShell file rendering collapse** - Fixed critical bug where PowerShell and other files without syntax definitions would collapse all content to a single line
+- [x] **Alt-tab/taskbar visibility on Wayland** - Fixed Ferrite window not appearing in alt-tab switcher or taskbar on Linux desktop environments (KDE Plasma, GNOME) running Wayland. Added `app_id` to ViewportBuilder.
