Allow plugins to bundle and register custom agents

CLI

What feature would you like to see?

Allow plugins to declare and register custom agents alongside skills, apps, and MCP servers.

The plugin spec currently supports three bundle types: skills, apps, and MCP servers. There is no way for a plugin to declare custom agents (~/.codex/agents/*.toml).

Plugins that rely on agent orchestration must work around this with a separate install step that converts agent definitions into skill files in ~/.codex/skills/.
On plugin install, Codex would register the bundled agents in ~/.codex/agents/ (or equivalent) so they're available for subagent spawning without consuming the skills budget.
