cargo-truce 0.43.0

//! Typed error enum for cargo-truce.
//!
//! Replaces the previous `Box<dyn Error>` blanket so callers can
//! pattern-match on the failure mode (missing tool, codesign failure,
//! manifest parse error, etc.) instead of string-grepping the
//! `Display` output. The catch-all `Other` variant carries any
//! still-stringly-typed errors from `Err("…".into())` sites the
//! codebase hasn't migrated yet — `From<String>` and `From<&str>`
//! conversions keep `?` propagation transparent during the migration.
