trusty-mpm 0.7.0

//! Compiled regex constants for the scrubber.
//!
//! Why: each regex is compiled exactly once at first use via `LazyLock`,
//! keeping the hot scrubbing path allocation-free.
//! What: one `static` per secret pattern (PEM, Bearer, JWT, sk-*, GitHub, AWS,
//! Google, Slack, connection-string). Path scrubbing uses char-scanners instead
//! of regexes because the `regex` crate lacks lookbehind support.
//! Test: each regex is exercised by the corresponding test in `super::tests`.
