echo

Hello-world brick for FocusMCP — returns the message it receives.

Its sole purpose is to serve as a smoke test of the FocusMCP pipeline: manifest parsing, brick loader, Registry, Router, EventBus. If echo_say responds, the whole plumbing works.

Also serves as a minimal template for brick authors: structure, manifest, tests, Changesets.
