ConsoleRunFrontend is dead code since the run moved to the server

[EdmondDantes]

Chore

Run/ConsoleRunFrontend.php has no constructor anywhere in src/ or tests/ — the run moved into the server in #92, and the terminal now tails over HTTP (HttpRunFrontend). The docblock on RunFrontendInterface:14 still calls it "the claw run frontend", which is no longer true and misleads the next reader about where a run's output comes from.

Acceptance

• The class is gone and the interface docblock names the frontends that exist.
