brand: an icon, ~/ and a block cursor

The app was a ring and a dot, drawn in CSS in the bar and inlined as a data
URL for the favicon. It now has an icon of its own: the `~/` of the prompt it
is named after, with the cursor waiting beside it in the alarm colour of the
theme. It is the favicon, a full-bleed touch icon for a phone's home screen,
and the mark in the bar, on the login and on the share page, served from
`web/public` so all of them are the same file.

The banner and a 512 px copy in docs/images are for the README and the wiki.
The crate description says what the workspace is now, not the diary it was.
