fix: complete Pezkuwi overlay + proper Nova merge

Pezkuwi overlay (B source):
- pezkuwi-chains.json: 4 chains (Relay, Zagros, Asset Hub, People)
- pezkuwi-xcm.json: full XCM config with networkDeliveryFee, networkBaseWeight
- pezkuwi-xcm-dynamic.json: dynamic XCM config

Merge script:
- Takes Nova as base (A source)
- Adds Pezkuwi entries to ALL XCM sections
- Pezkuwi chains appear first
- Nothing gets deleted

All chains have disabledCheckMetadataHash: true
