CatPaw v0.2.0

From an agent's report of using CatPaw on a NAS:

• Downloads are saved to disk as they arrive, in ~/Downloads/CatPaw by
  default: no longer kept in memory and cut off at the response limit,
  so large files work. The navigation answers at once with where the file
  goes, wait({"for":"download"}) waits until it is saved, and the
  download view of read says how far it is.
• settings, a new tool: shows CatPaw's settings and changes them, the
  user approving each change, which is saved in settings.json next to
  the approval key: downloadDir, and localAddress, the address the
  hand-off and approval pages listen on when the user's browser is on
  another machine (they listened on 127.0.0.1 only). --download-dir,
  --local-address and --settings-file set them from the command line.
• The agent can take a hand-off back (handoff with end: true) when the
  user cannot reach the page or will not finish, what they typed staying
  masked; and a tab with the user can be closed.
• Switching tabs shows what changed since the agent last saw the tab
  (snapshot: "full" or "none" for the rest), not the whole page.
• Clicks go through what does not take the pointer: a box with
  pointer-events: none (a decorative overlay over a button) or
  visibility: hidden is not hit, its children may be; clicks no longer
  stop at "covered by" such a box.

The library crates' public types changed (responses carry a saved file,
requests a download), hence 0.2.0.

The scripts download the archive for your system from this release and
check it against SHA256SUMS. Or download an archive below, check it
(sha256sum -c SHA256SUMS --ignore-missing), and put catpaw on your
PATH. Then connect it to your agent:

catpaw setup claude-code

Intel Macs and other systems: cargo install catpaw (Rust 1.91 or
later) builds it, see the README.
