agent-fleet 0.2.1

Changed

• The PyPI distribution is named fleetq (pipx install fleetq): PyPI refuses agent-fleet
  because agentfleet already exists. The command is still fleet, and the repo, skill and plugin
  are still agent-fleet.
• Added .github/workflows/release.yml, a manual trusted-publishing (OIDC) workflow for PyPI.

Install: pipx install fleetq then fleet install-skill.
