//! Mode-picker integration test.
//!
//! The `skills/new-agent` wizard Phase 3.6 appends `mode-*` block names to
//! the `blocks` array. This test locks the contract that such a manifest
//! validates cleanly AND the expected mode files ship in `_blocks/` (either
//! in the fixture set or alongside the real kit).
//!
//! We use the real `_blocks/` so the test protects the kit's mode surface —
//! if anyone renames or deletes a mode block, the wizard's Phase 3.6
//! selection would silently break at runtime otherwise.
