//! Core tool execution runtime for Statespace.
//!
//! Provides tool parsing, frontmatter extraction, command validation,
//! and sandboxed execution with security protections (SSRF, path traversal).
//!
//! ```rust,ignore
//! use statespace_tool_runtime::{BuiltinTool, ToolExecutor, ExecutionLimits};
//!
//! let tool = BuiltinTool::from_command(&["cat".to_string(), "file.md".to_string()])?;
//! let executor = ToolExecutor::new(PathBuf::from("./toolsite"), ExecutionLimits::default());
//! let output = executor.execute(&tool).await?;
//! ```
