//! End-to-end proof for manifest-declared tools (EPIC 12.11): a plugin that
|
|
//! ships a `[[tools]]` entry is discovered, registered as a native MCP tool
|
|
//! **without forking** `build_registry()`, and invocable as a sandboxed
|
|
//! subprocess. Own integration-test binary so the global plugin registry
|
|
//! (`OnceLock`) is fresh. Unix-only: the tool is the `cat` echo binary.
