v1.1.3 of cockpit

Host-side tooling for flutter_cockpit task execution and artifact handling. Changelog excerpt: - Removed the hosted CLI/MCP package dependency on the Flutter SDK by moving shared control, evidence, recording, runtime, and bridge DTOs to the pure Dart flutter_cockpit_protocolpackage. - Fixed pub.dev global activation and project-local dart run cockpit:cockpitso development supervisor startup works from both installation modes.
