Module config 

Configuration trait and validation types for mcpr modules.

Each mcpr module (store, cloud, tunnel, logging, etc.) implements ModuleConfig on its TOML config section struct. This lets every module own its own defaults, validation logic, and documentation — while the CLI orchestrates validation by iterating over all registered modules.

Design rationale

Without this trait, all config validation lives in one monolithic function in mcpr-cli/src/config.rs, and every new module must touch that file. With it, each crate validates itself — the CLI just loops over &[&dyn ModuleConfig].

Structs

A single validation issue found in a module’s configuration.
