feat: add native-credit-pool yields

[June-native]

Add Native Credit Pool adapter

Adds a new adapter for Native Credit Pool, a new form of DEX LP, offering single-sided, no-loss LP positions via rebasing tokens.

More info: https://docs.native.org/native-dev/solution/native-credit-pool

Summary

• Fetches APY data from Native's API for all supported chains. (Native Credit Pool LPs are Lido-style LST rebasing yield tokens; yield is distributed weekly/daily and reflected in exchange rate changes. To avoid failing to fetch exchange rate retrospectively due to rpc issue, we opted for relying on Native side's API, following Lido's template)
• Calculates TVL on-chain using totalUnderlying() on LP token contracts
• Batched RPC calls

Supported Chains

• Ethereum
• BSC
• Arbitrum
• Base

Implementation Details

• multiCall for on-chain data fetching
• Fetches token prices from DefiLlama API
• Includes individual pool URLs linking to Native's app for direct deposits
