Constant HAS_BUNDLED_CLI 

pub const HAS_BUNDLED_CLI: bool = false;

true when this build of the SDK has the Copilot CLI embedded in its binary — i.e. the bundled-cli cargo feature is on and the target platform is one for which build.rs shipped an archive.

Useful for branching on bundling presence without forcing the lazy extraction triggered by install_bundled_cli.
