0.3.21: finished sub-agents go in a book

0.3.21 is out. The envelope that held finished sub-agents is a little green book now. When a sub-agent finishes, the book on its session's row says how many are new. Open it and each one is a document named like a .md file, with who wrote it, how long ago and the first two lines. Read all shows what it was asked and everything it handed back.

Markdown shows the way it was written. Headings and bold read bold, code is shaded, and the marks stay in place but faint, so nothing gets eaten. A document stays new until it has been on screen for about five seconds, so it doesn't fold away while you're still reading.

Also a volume slider in Settings > Sounds, up to 125%, because the crew was too loud over a movie.

Update from the About tab in the app's settings, or brew upgrade --cask agent-valley.
