Remove the Host executor in favor of quire-ci
The in-process pipeline execution path was a second copy of what quire-ci
already does in a subprocess. Keeping both meant every runtime change had
to be made twice and the test surface was doubled.

- Removed Run::execute and 14 tests that exercised it
- Removed the JobFailed error variant (only used by Host path)
- Removed unused imports (Rc, Pipeline, RunFn, Runtime, RuntimeHandle, ShOutput)
- Rewrote the `ci run` CLI command to dispatch via execute_via_quire_ci
- Updated the trigger_creates_run_and_completes integration test to
  account for quire-ci not being on PATH in test environments
- Kept the Executor enum and :executor config key for a future Docker
  executor
