Agent Instance Deployment

Deployment target for agents.Agent instances. Transforms each Agent into its target client's on-disk file format (markdown-with-frontmatter for Claude Code and Gemini CLI, TOML for Codex) and writes it to the client's projectAgentDir or userAgentDir as declared on the selected agent-skills.Client. The CLI registers an AgentDeploymentHandler under this instance's canonical URI to perform the actual materialization.
