Per cleanup decision: HERDR-HUB-RUNBOOK.md is stale (Herdr is now an optional
Linux UI only, not a hub), and T1.4-CACHE-WARMING-DESIGN.md is superseded (cache
warming is implemented via config flags). Also drops the now-dangling link to the
latter from COLIBRI-TOKENOMICS-TRIFECTA.md.
Kept (still useful): ISO-INTEGRATION-PLAN.md, CLAWDIE-STUDIO-PROPOSAL.md.
