Rules

• cli.rs stays in vtcode-core (depends on crate::cli::input_hardening).
• Re-export facade in vtcode-core (mcp/mod.rs) must stay in sync.
• rmcp_client is pub(crate) -- not part of the public API.
• convert_to_rmcp() is pub(crate) -- internal JSON bridge.

Gotchas

• enhanced_config.rs uses #[cfg_attr(feature = "schema", derive(schemars::JsonSchema))].
• rmcp-reqwest is a renamed reqwest with rustls features -- not the same as the workspace reqwest.
• DEFAULT_ENV_VARS is platform-conditional (#[cfg(unix)] / #[cfg(windows)]).
