feat: add Nova-base sync mechanism

- 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.
