* Support starting from altair * hide `finalized-checkpoint-` - they are incomplete and usage may cause crashes * remove genesis detection code (broken, obsolete) * enable starting ChainDAG from altair checkpoints - this is a prerequisite for checkpoint sync (TODO: backfill) * tighten checkpoint state conditions * show error when starting from checkpoint with existing database (not supported) * print rest-compatible JSON in ncli/state_sim * altair/merge support in ncli * more altair/merge support in ncli_db * pre-load header to speed up loading * fix forked block decoding
