- Fix SQL column reference in vault hooks: use (t.defaults->>'inceptBlock')::bigint instead of t.incept_block - Correct import paths in staking pool hook (6 levels deep) - Fix price extraction to destructure priceUsd property - Wrap decimals in Number() for bigint type compatibility This resolves snapshot extraction failures that prevented staking data from being indexed.

lgtm. let me merge tho. indexing the pools will take some time, so we need to disable the fanout cron, index the pools manually, then re-enable the cron.

Summary
Implements staking rewards data indexing for Yearn vaults across multiple chains. This adds support for four types of staking systems (VeYFI, Juiced, V3 Staking, OP Boost) using an event-driven discovery pattern, and embeds staking APR and reward data directly in vault snapshot hooks.
Closes #305
