PR Summary

Introduces chain-scoped, incremental daily token volume computation and a unified cross-chain view.

• New incremental dex_<chain>_token_volumes_daily models (e.g., arbitrum, base, ethereum, polygon, zksync, etc.) aggregating bought/sold flows into daily volume_raw, volume, and volume_usd
• Adds data tests in _schema.yml for each chain ensuring uniqueness on (blockchain, token_address, symbol, block_date)
• New unioned view dex_token_volumes_daily and alias view tokens/dex_volume_day exposing all chains
• Minor _schema.yml cleanups (newline/indent fixes)
• Sets vars.dev_dates: true in dbt_project.yml to limit scan in dev mode

hey @alicecha - just added a few minor comments

[tomfutago]

just this instead of CASE..WHEN?

NULLIF(COALESCE(bought_volume_raw_sum, 0) + COALESCE(sold_volume_raw_sum, 0), 0)

[alicecha]

The thing is I would like it to default to NULL if both supply and bought are NULL

proactive approval, but agree with tom feedback on macro usage.
