v0.5.18: chore: 0.5.18 (#210)

• A run can now take over a window that is already open, in Chrome or in an Electron app such as VS Code or Slack.
  --attach (or attach=True in run_task) skips opening a tab and drives an existing page, and --target-match TEXT picks the first page whose title or URL contains TEXT. The window stays open after the run, and with no
  --start the run begins on whatever the window already shows. --cdp-port PORT finds the browser from its
  DevTools port, which is how an Electron app started with --remote-debugging-port is reached. connect_cdp()
  hands a script the same attached page, without the agent. Windows an Electron app opens on its own join the run
  only with --target-match, because in a browser such a window is as likely a tab someone opened by hand.
