feat: route root-level commands to plugins in ~/.picoclaw/plugins

- Added root args validator to picoclaw command to route unknown
  commands to plugins (e.g., picoclaw service → picoclaw-service)
- Removed built-in 'plugins' subcommand - now handled as plugin
- Added prefix matching to support 'picoclaw-X' → 'X' shorthand
- Added exported functions (FindPlugin, ExecPlugin, ListPlugins)
- Updated tests for new command structure

Example usage:
  picoclaw service status    → runs picoclaw-service
  picoclaw launcher          → runs picoclaw-launcher
  picoclaw plugins-list      → runs picoclaw-plugins-list
