Fixed: opening a file or its folder from the popup. Download errors now stay visible in the list. Popup contrast, buttons and notices polished in all 11 languages, with a confirmation before clearing history.

New in 0.8.0
- One-line Windows installer that verifies a minisign signature over the release checksums before running anything.
- Simpler first run: copy the install command from the popup, paste it in PowerShell and the component connects automatically.
- Romanian messages for the computer component.

Fixed
- The installer only needs winget when a dependency is missing, and rejects 32-bit Windows.
- The popup handles a failed component check instead of staying silent.
- A duplicated key in the locale files that made them invalid JSON.
