feat(agent): add command-execute skill for intelligent command dispatch

- Enhance run_plugin_command tool to support all registered commands (system preset + plugin + other), not just plugin commands
- Add list_all_commands tool to discover all available commands with descriptions and categories
- Add command-execute skill that guides the agent to recognize user intent from natural language and match it to available system/plugin commands
