/// The primary entry point for the Zoi CLI and its intelligent shims.

/// Multiplexing Logic:
/// Zoi uses a single binary for both the main CLI and all tool shims.
/// - If the binary is invoked as `zoi`, it runs the standard CLI.
/// - If it is invoked via a symlink (e.g. `node` -> `zoi`), it acts as a "Shim".
/// - In shim mode, it dynamically resolves the correct version of the requested
///   tool based on the current project context, environment, or plugins.
