- Double-clicking a file or choosing the new 'Öppna' context-menu item
asks TUI-WM to open it via $TUI_WM_SOCKET (open_file), inheriting
the user's file associations and default editor
- Outside TUI-WM the configured text_editor is used instead: the TUI
suspends, runs the editor on the same terminal and resumes
- Directories keep navigating as before

⬆ (U+2B06), 🖼 (U+1F5BC) and ⚙ (U+2699) are East-Asian-Width
Neutral: unicode-width measures 1 column but emoji fonts draw 2, so
every row containing them shifted right by one column. Replaced with
真 Wide emoji (📷, 🔩, ⚡) or pure text glyphs (↑, ≡), plus a
regression test asserting every emoji icon measures 2 columns.
