Module native_skills 

Built-in native skill implementations.

Embedded in the runtime binary and available without any external tooling. New tool categories are feature-gated by their config section:

• File tools → native_tools.file_tools_enabled
• Web fetch → native_tools.web_fetch_enabled
• Terminal → native_tools.terminal_exec_enabled
• Session search → native_tools.session_search_enabled
