fix(#1107): progress consults verification.status before reporting a phase complete (#1116)

/gsd-progress derived phase completeness from plan/summary counts only and never
consulted the verification.status query (the #651 seam), so a phase whose
VERIFICATION.md ended human_needed or gaps_found was reported complete and
routing skipped to the next phase. Add Step 1.7 (consult verification.status for
the current phase) and routing rows that send gaps_found to plan-phase --gaps
(Route V.gaps) and human_needed to verify-work (Route V.human) before the generic
complete row. passed/missing/unknown still route as complete so unverified phases
are not falsely blocked.

Closes #1107
