Copilotkit Self Update

When your CopilotKit agent's skills are showing outdated API names or wrong information, this runs a single npx command to pull the latest skill definitions from GitHub. It's specifically for refreshing the SKILL.md files that teach your agent about CopilotKit, not for updating your actual project code. Works across Claude Code, Cursor, and other tools automatically. The command does a fresh clone every time so you always get current versions. You'll need to restart your session afterward to pick up the changes. Honestly most useful when CopilotKit ships new APIs and your agent is still suggesting the old ones, or when you first realize the skills can get stale.
