Mohammed Olabie cffd24dea4 cmd/docker: print command error before running plugin hooks
Plugin hook output (such as Gordon's "What's next:" hint) was rendered
before the command's own error message because hooks were invoked inside
runDocker while the error was only printed in main() after runDocker
returned.

Print the error to stderr before invoking the hooks, and replace the
error with a status-only StatusError so main() does not print the same
message a second time. The original error message is captured up-front
and still passed to the plugin hooks.

The inline error-printing block in runDocker is extracted into a
printCommandError helper so the new behavior can be unit-tested
directly without spinning up runDocker.

TestPrintCommandError covers each branch of the helper: nil error,
generic error (printed and replaced with StatusError), StatusError
with/without message, context.Canceled (raw and wrapped), and
errCtxSignalTerminated.
