DR-042 Phase A: expedition-driven win — move win-driver off base-siege survival, kill the AFK path

Design-review-gated (wf_ebef4e81-dba, GREEN-WITH-CHANGES). The win-driver moves
from "survive N base sieges" to "clear N expeditions". The review overturned the
literal plan: credit on RETURN, not at the clear edge (clear-edge crediting arms
the undefended final base siege -> uncontestable terminal Loss).

- ExpeditionGateSystem: now the sole production writer of GoalProgress.Charge —
  a clamped +1 per cleared expedition folded into the existing once-per-epoch
  reward block, reusing the LastRewardedEpoch latch (Ore + Charge share fate) +
  a SaveRequest checkpoint. No new latch, no new GhostField, no ordering change.
- CyclePhaseSystem: deleted the survived-siege +1 (the AFK win path). Victory
  latch unchanged; GoalReached still arms the final base siege at cap.
- CycleDirectorAuthoring + CycleDirector.prefab: ScheduleEnabled baked OFF
  (retaliation-only). A serialized prefab bool ignores the C# field initializer,
  so the value is flipped in the prefab, not just the code default.
- Tests: re-pointed CyclePhaseSystemTests + EndgameWinLoseTests survived-siege
  assertions; extended ExpeditionGateRewardTests (+1, no-double-credit, clamp).
  389/389 EditMode green; clean netcode Play smoke (no sort-cycle, Schedule=0).

SaveData stays v5. Docs: DR-042 build record + forks resolved, CLAUDE.md
base-loop line, Backlog (A done).
