BOLT-1268 P3 — explain+resolve Bugbot Net Grid Energy thread on PR #12204

Bugbot thread PRRT_kwDOJpxUwM6JPJzZ flags the Net Grid Energy KPI removal as out-of-scope per the original PR body. The removal IS intentional — Richie explicitly asked for it on 2026-06-12 because Reports is canonical for grid energy and the values do not reconcile between the two views. Reply explaining the design decision (linking Richie message ts 1781293585.881699 implicitly via the rationale) + resolve. Do NOT revert the removal. Also confirm Bugbot thread PRRT_kwDOJpxUwM6JOrKS (hour params fix) is properly resolved given sub-agent claimed it was.
