netsuke-build 0.1.0-beta2

//! Standard library registration for `MiniJinja` templates.
//!
//! Wires file tests, path helpers (including the `which` filter/function),
//! collection utilities, time helpers, network helpers, and command wrappers
//! into a single entrypoint so templates behave consistently across projects.
//! Configuration and registration helpers are re-exported to keep integration
//! points discoverable: `StdlibConfig`, `NetworkConfig`, `register`,
//! `register_with_config`, and `value_from_bytes`.
