- Add blocked-chains.json with DNS-failing endpoints (AlephZero, InvArch, Quartz, Passet Hub Testnet)
- Update merge-chains.py to filter PAUSED chains, testnets (except Pezkuwi), and broken RPCs
- Reduce chain count from 102 to 86 (4 Pezkuwi + 82 working Nova chains)
- This fixes staking page not loading due to DNS resolution failures
- Add sync_from_nova.py script to merge Nova chains with Pezkuwi overlay
- Add GitHub Action for daily auto-sync
- Sync all chains from nova-base (includes Polkadot Coretime and other missing chains)
- Pezkuwi chains appear first and take priority
This fixes DOT swap crash caused by missing Polkadot Coretime chain.
