//! Built-in tools for the Insomnia LLM agent.
//!
//! Implements Read / Write / Edit / Glob / Grep / Bash on top of the
//! `llm-worker` `Tool` infrastructure. Filesystem access is mediated by
//! two orthogonal concerns:
//!
//! - [`ScopedFs`] — pod-lifetime, expresses the write-block boundary for
//!   the current scope. Derived from the manifest and shareable across
//!   sessions.
//! - [`Tracker`] — session-lifetime, enforces the "read before edit"
//!   policy via content hashes and tracks the recency of touched files.
//!   Recreated fresh per session.
//!
//! The Pod layer owns both instances and passes them to
//! [`builtin_tools`] when registering tools on a `Worker`.
//!
//! `Bash` is the lone exception — its child processes bypass `ScopedFs`
//! entirely. Safety for arbitrary command execution is delegated to the
//! Permission layer (deny/allow rules on the command string).
