`crewai deploy create` counts every attempt (`Create Crew Deployment`) and every
success (`Crew Deployment Created`), but the gap between them carried no cause:
among clients able to emit the success span, the CLI succeeds 96.7% of the time
and the run TUI 36.4%, and nothing said why. A third span, `Crew Deployment
Failed`, now fires for every failure after the attempt is counted, with a closed
vocabulary `reason` (api_4xx, api_5xx, invalid_response, network_error,
zip_error, user_declined, unexpected), the HTTP `status_code` when the API
answered, and the existing `source`. Never the error message.
The request path is factored into `_request_crew_creation`; every exception is
classified, reported and re-raised unchanged, so CLI and TUI behaviour is the
same as before. HTTP failures are classified before `_validate_response`, which
still prints and exits as it did.
