Add Wealthville to DeFI resources

[amitesh-m]

Adds one entry to the DeFI section, alongside the recent analytics/API additions (pigi.finance, Formo).

Wealthville is a scoring layer for liquidity pools, aimed at developers building LP or yield strategies who need a judgement rather than raw TVL and volume to interpret themselves.

• Coverage — Uniswap v2/v3/v4, Aave, Morpho, Pendle, Curve and Compound across Ethereum, Arbitrum, Base, Optimism, Polygon and BSC, plus Meteora, Orca and Raydium on Solana.
• Output — a 0-100 score and an Enter/Hold/Exit/Reduce/Avoid verdict, with confidence calibrated per protocol rather than pooled across all of them.
• Graded after impermanent loss, not on headline APR — which is where most yield numbers mislead.
• Miss-inclusive track record at /api/v1/track-record: hit rates and failures over a rolling 30 days. Currently ENTER 0.63 across 3,043 resolved calls, EXIT 0.69, and REDUCE 0.00 on n=16. The weak class is published on purpose.

Free, keyless REST API with a public OpenAPI spec, plus a read-only MCP server for agent use. No signup.
