Record Hyperplan evaluation as a no-change row, not a dedicated file

Hyperplan (OMO adversarial multi-agent planning) was evaluated: no
change. Its value is a multi-agent runtime (agent swarm + team_* tools),
which hits two standing non-goals; its methodology layer overlaps
existing lenses; three possible gaps (defend/refine/concede, evidence
grade, assumption ledger) are not promoted (gate unmet).

Record it the same minimal way as Loop-Skill / preflight / Record&Replay:
a row in the consolidated external-adoption case study plus a Decision
Index pointer — not a dedicated per-tool reflection file, which would
contradict this case study's own Rejected Alternatives. Drop the
dedicated file, repoint both references to the case study, regenerate
index.

Verified: project-knowledge, links, lint, governance, 52 tests all pass.
