Find Rust error types with hand-written Display/Error/From impls and refactor them to derive thiserror::Error, preserving behavior.

Replace string-matched error classification with typed domain errors, value objects, and explicit boundary mappings. Use when code derives behavior from error messages, substrings, magic prefixes, loosely typed status strings, denial reasons, protocol categories, validation messages, or other stringly typed logic that should be represented at the data type level.
