Lint the PATH environment variable against declarative ordering rules.
Documentation
//! Drift gate for the checked-in `schemas/pathlint.schema.json`.
//!
//! The schema is generated from the live Rust types via schemars,
//! and committed to the repo so editors / Schema Store can fetch it
//! by raw URL. Whenever the `Config` / `Expectation` / `SourceDef` /
//! `Relation` types change, this test fails until someone runs:
//!
//!     cargo run --bin gen_schema > schemas/pathlint.schema.json
//!
//! and commits the new bytes. That is by design — the checked-in
//! schema must always match what schemars would produce against
//! the current parser.
