feat: re-platform agentic review onto executus + large-PR cost controls (#20)

Makes gadfly a consumer of executus (run.Executor compaction/bounding/budget/critic + fanout) and fixes the large-PR token burn in size-gated layers: paginated get_diff, downshift above GADFLY_HUGE_DIFF_BYTES, and a swarm-wide GADFLY_PR_BUDGET_SECS backstop. Small PRs untouched; advisory-only and the static binary preserved. Dogfood swarm reviewed it (6 models, 21 real findings graded + folded in).
