The CLI help text and inline comments incorrectly stated that -c key=value flag parses values as JSON, when the implementation actually uses TOML parsing via parse_toml_value(). This caused confusion when users attempted to configure MCP servers using JSON syntax based on the documentation. Changes: - Updated help text to correctly state TOML parsing instead of JSON Fixes #4531

This crate is designed for utilities that need to be shared across other crates in the workspace, but should not go in core.
For narrow utility features, the pattern is to add introduce a new feature under [features] in Cargo.toml and then gate it with #[cfg] in lib.rs, as appropriate.
