Turnscope 0.1.3

• The app's engine works out the status again only after reading
  something new, even with a history file it can't read. Such a file made
  it work out the status after every change in an agent's folder.
• doctor no longer lists a history file that couldn't be read once
  it's deleted, and counts an OpenCode message it can't read once, not
  again on each read for the 10 seconds after it.
• Connecting an agent is refused while Turnscope's engine runs from its
  disk image or another drive. Moved to Applications and opened within a
  minute of quitting the one on the disk image, the app could still connect
  an agent to that one, which is gone once the image is ejected.
• Claude Code usage from a backend that sends an empty cache split
  counts its cache writes.
• Search quotes the message it found with a quote or backslash in it
  escaped, as the rest of a session's text within a line is. A " in it
  could end the quote early, so its words read as Turnscope's own.
• Your agents' history is read again once after updating, so these fixes
  apply to what was read before.
