feat(harness): port memory/search/evidence/db/decision cmd (Onda 3.2)

5 cmd foglia portati con rename + drift fix:
- memory_cmd: portato col modello registry INTATTO (TODO marker per il drop registry
  decisione spec 5 — task separato, richiede L2 per validare il rewrite su vectordb)
- search_cmd: creata search_app sub-app (era funzione standalone in ChironeWp3),
  registrata come 'tht search find'
- evidence_cmd, db_cmd, decision_cmd: port verbatim

Drift fix decision_cmd: DECISION_MIN_PHASE.get(type,1) -> load_workflow().decision_min_phase(type).
Check grep-per-file: ~15 residui nsp/PSD_SSL_CA nei messaggi utente fixati (nsp <cmd>
-> tht <cmd>, nsp.yaml -> workspace yaml, PSD_SSL_CA -> THT_SSL_CA).

Suite: 165 passed. tht --help ora mostra 10 sottocomandi.
