- Rename directory to CIP-0180
- Restore protocol_version minor field (intra-era HF signaling post-Dijkstra)
- Wrap producer_agent in extensible informational_data_set array per Martin's suggestion
- Change producer_agent min size from 0 to 1 (nil already handles opt-out)
- Lock era to Dijkstra (remove "potentially")
- Simplify: remove analytics use cases, usage examples, verbose CBOR examples,
  phased implementation plan, and unenforceable 60% adoption metric
- Update limitations to focus on block-production-only visibility
