[dioptx]

Manual mappings and metadata:

• Added mappings in resources/manual_chain_mappings.csv for chain ID conflicts, display names, and provider entities.

New ingestion assets:

• Introduced daily assets (l2beat_daily, defillama_daily, dune_daily, bq_op_stack_daily, bq_goldsky_daily) in chain_metadata.py for fetching and deduplicating chain data from sources like L2Beat, DefiLlama, Dune, and BigQuery.
• Added aggregated_daily to combine data for daily partitioning and validation.

CLI updates:

• Improved build_metadata command in app.py for usability and logging, replacing the old command.
• Created chains_app Typer application for chain commands.

Testing:

• Added scripts/test_real_loaders.py for testing chain metadata with live data.

Code organization:

• Improved imports and modularity in app.py by reorganizing modules.

Summary: Updated mappings, ingestion assets, CLI, testing, and code structure for improved data management and usability.

Architecture:

and also just decide if a dtype check is necessary on the column
