Added support for custom agents. Custom agent definitions are pulled from ~/.copilot/agents, .github/agents in your repository, or your organization's .github repository. You can explicitly invoke an agent with the /agent slash command interactively or --agent <agent> noninteractively. Agents are also provided as tools that the model can call during completion of a task
Added a /delegate command to delegate a task asynchronously to Copilot coding agent. Any unstaged changes will be committed to a new branch, a PR will be opened in your GitHub repository, and Copilot will complete work in the background.
