Release 0.4.0

### Added - The Settings sidebar shows the app's version under its links, and every page names it in a `version` meta tag, so you can check which release a deployment runs, even without signing in. - Jump to has a Show replies toggle that lists the assistant's replies between your messages, so you can jump straight to a reply. It is remembered on your device. ### Changed - When your chats are open in another tab, the chat now blurs behind a card in its middle that explains why, with Use here as its button, rather than a line of plain text. The same goes for when this device's copy of your chats couldn't open.
