VaultInk 0.64.0

Search in Browse Files, a safer Random page!, and phone-to-reader typing and sync (kos25k #13, #15).

• Browse Files has a magnifier: it looks for files and folders by name across the card, and a hit opens or shows in its folder. It says when there may be more.
• Random page! only picks book formats, not notes, logs or the changelog, and a peek no longer lands on the Continue card or in Recent.
• Book info no longer repeats the title or author in the file name.
• The text keyboard has a From phone button: the companion app leaves text on the card, and it is typed in for you.
• The companion app can ask for a LiveSync sync at the next wake.
• Compressed Excalidraw drawings open.

Companion 0.5.0 (separate release): intro screen, About, built-in documentation, file types in the Files list, a Greek Up button that no longer wraps, Google Keep import.

Tried in the simulator and on the computer (host tests, device build). Not tried on a real device, with a Bluetooth keyboard or a wheel.
