feat(harness): require_phase_or_exit + phase advance/reopen/show (Onda 1.2)

require_phase_or_exit: guard riscritto vs Workflow (load_workflow().phase_name invece
della costante PHASE_NAMES drift). Exit 1 se la sessione e' sotto soglia. Usato da
cte/decision/datamart cmd.

Comandi phase (portati + adattati al modello ThothII, non copia cieca):
- advance: persiste phase_approved; --auto exit 6 se la fase non e' completa
  (contratto col gate)
- reopen: persiste phase_reopened + teardown_to_phase degli artefatti oltre il target
- show: stato sessione (fase corrente, ultime decisioni)

session_dir helper tenuto qui (mirror di session_cmd) per evitare circular import.
_cfg() fa fallback a THT_WORKSPACE env finche' _load_config_or_exit (Onda 1.4) non
sara' portato.

L1: 4 test require_phase_or_exit (allow at/above, exit below, message con nome fase
dal workflow). Suite: 161 passed.

"""L1: require_phase_or_exit — the phase-gate guard rewritten vs Workflow.
Used by cte_cmd/decision_cmd/datamart_cmd to refuse an action when the session
hasn't reached a phase yet. The rewrite replaces the old PHASE_NAMES constant
with load_workflow().phase_name(). Exit code 1 (typer.Exit) when below threshold.
