Fix Copilot review findings: broken paths, stale refs, horizon count

- endocrine/AGENTS.md, ichor/AGENTS.md: fix devCorrectionLog relative
  path (../../ → ../../../) so it resolves to repo root .claude/
- bus-topology.md: update stale M2/M6 references to current specs
  (M2=Data Feeds, M6=Conductor)
- M3a: combine tick/hourly to match hub's six-horizon convention
