samagotchi 0.89.0

Added

• chi bundle try PATH -p TEXT runs one real model turn in an isolated sandbox with the bundle and shipped
  guardrails installed and a $1 cost cap; --json exposes an experimental machine-readable trace.
• chi bundle install --dev PATH installs a bundle you are writing as a link to its folder: edits to its plugin,
  hooks, rules and scripts apply at the next session with no re-install, and their sha256 isn't checked (that
  bundle only). Memories are copied; re-install with --force to pick up memory edits. A re-install from the same
  PATH prunes dropped hooks. It refuses chi-shipped bundles and profiles and warns when a linked script needs
  chmod +x. upgrade refuses it; uninstall never touches PATH. chi bundle status shows dev → PATH (missing)
  if the source is gone.

Changed

• minitest is now a dependency of the gem, so chi bundle test runs a bundle's Minitest tests (and the one
  chi bundle new writes) on a slim or vendored install without gem install minitest.
