fix: sweep every remaining synchronous Agent-dispatch site with run_in_background: false

The #2440 failure shape was a silently-missing review voice — a
specialist launched in the background and merged before it completed.
Every remaining synchronous dispatch site now carries the explicit flag:
the Red Team dispatch, the spec review loop, the Codex
second-opinion/plan-review/doc-review Claude fallbacks, the adversarial
subagent, design sketch and outside voices, autoplan's design/eng/dx
phase dispatches, CSO parallel finding verification, and design-shotgun's
variant launch. Parallel fan-outs stay parallel — multiple foreground
Agent calls in one message run concurrently (the shipped v1.64.0.0
review-army pattern).

GENERATED_WITH_GUIDANCE now pins all 24 generated carriers, so a new
dispatch site that drops the flag fails the free suite. Six carved-skill
skeleton ceilings re-measured and ratcheted (~80-130 B growth each);
factory ship golden re-rendered.
