Release v0.2.4

NerazimNet v0.2.4

Improvements

• Remote Port auto-fills in Add Tunnel. Prefills with the next free port — max(used)+1 across every tunnel's remote_port and extra_ports remote sides (range upper bounds included), or 10000 for your first tunnel. Always editable; Local VPS Service routes are skipped since that field is the app's own port.
• Documentation screenshots refreshed. 19 images recaptured on the new theme — installer wizard, first-run dialogs, empty views, all Settings tabs, collapsed sidebar, tray icon + menu, and the Add Server/Tunnel dialogs. A few slots (populated dashboard, edit dialogs, provisioning dialog) still use older captures.

Bug Fixes

• Ctrl+C no longer orphans Syncthing. Interrupting the app in a console now runs the normal shutdown path — previously syncthing.exe kept running with its executable and ports locked.
