fix(desktop): respect local-origin tauri shell for directory access (#391)

* feat: enable local-origin desktop features and copy in terminal support

- Enable arbitrary web loads in desktop web content for TAURI apps.
- Guard directory dialog access behind local-origin origin check.
- Add copy-to-clipboard support for terminal selections via common shortcuts.

* fix: improve initial directory resolution and persistence in directory store
