fix(parity): 3 divergencias TS↔Go destapadas por la auditoría de cobertura

Encontradas por el workflow parity-coverage-audit (huecos de cobertura que
escondían bugs), verificadas contra el oráculo TS:

- up --workspace-mount-consistency: faltaba validar el enum
  [consistent,cached,delegated]; Go pasaba cualquier string a docker. Ahora
  se valida como en TS (yargs choices). -> exit 1 = TS.
- features/templates package|publish --log-level: StringVar sin validar;
  MapLogLevel defaulteaba silenciosamente a Info. Ahora rechaza fuera de rango
  [info,debug,trace] (collectionCommonUtils/{package,publish}.ts). -> exit 1 = TS.
- features resolve-dependencies sin features: Go imprimía {"installOrder":[]}
  exit 0; TS escribe 'Could not parse features object...' a stderr y exit 1
  (resolveDependencies.ts:92-93). Corregido, mensaje idéntico.
