ServiceScale and ReplicaNumbers join the vocabulary: replica counts and
numbering read from container labels replace counting 'Started' lines
in the CLI output.
- TestScaleDownNoRecreate's final assertion now actually runs: the
legacy test built the scale-down command without executing it, so
'scale down removes obsolete replicas' was never exercised; the
scenario locks the real behavior (stale replicas dropped, up-to-date
ones kept, whatever their numbers).
- secrets scenarios inline the include-based project (compose.yaml,
child project and env_file as one txtar archive).
- TestRawEnvFile and TestRunEnvFile inline their env files;
TestUnusedMissingEnvFile stays legacy for its completion assertions,
which drive the plugin/standalone binaries directly.
- Fixtures scale/, env-secret/ and dotenv/raw are removed.
