Add InsumerAPI action provider for on-chain wallet verification and trust profiles

Privacy-preserving on-chain verification across 32 chains (30 EVM + Solana + XRPL).
Returns ECDSA-signed boolean attestations — never exposes raw wallet balances.

5 actions:
- verify_wallet: 1-10 conditions per call, optional Merkle proofs, JWT format
- get_wallet_trust_profile: 17 checks across 4 dimensions (stablecoins, governance, NFTs, staking)
- get_batch_wallet_trust_profiles: up to 10 wallets, 5-8x faster than sequential
- validate_discount_code: public endpoint, no API key required
- list_compliance_templates: Coinbase Verifications + Gitcoin Passport templates

+# Insumer Action Provider
+
+This directory contains the InsumerAPI action provider implementation, which provides actions for privacy-preserving on-chain wallet verification, trust profiling, and discount code validation across 32 chains (30 EVM + Solana + XRPL).
+

+```
+
+## Setup
+
+1. Get a free API key at [insumermodel.com/developers](https://insumermodel.com/developers/)
+2. Set the `INSUMER_API_KEY` environment variable, or pass `apiKey` in the config
+
+```typescript
+import { insumerActionProvider } from "@coinbase/agentkit";
+
+// Via environment variable
+const provider = insumerActionProvider();
+
+// Via config
+const provider = insumerActionProvider({ apiKey: "insr_live_..." });
+```
+

+  - 1 credit per call (2 with Merkle proofs)
+
+- `get_wallet_trust_profile`: Generate a wallet trust profile
+
+  - 17 checks across 4 dimensions: stablecoins, governance, NFTs, staking
+  - ECDSA-signed and independently verifiable
+  - 3 credits per call (6 with Merkle proofs)
+
+- `get_batch_wallet_trust_profiles`: Batch trust profiles for up to 10 wallets
+
+  - 5-8x faster than sequential calls
+  - Supports partial success
+  - 3 credits per wallet

+
+  - No API key required (public endpoint)
+  - Returns validity, discount percentage, and expiration
+
+- `list_compliance_templates`: List available EAS compliance templates

+## Examples
+
+### Verifying Coinbase KYC Status
+
+```
+Prompt: "Check if wallet 0xd8dA...96045 has Coinbase KYC verification on Base"
+
+The agent will call verify_wallet with:
+- wallet: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
+- conditions: [{ type: "eas_attestation", template: "coinbase_verified_account" }]
+```
+
+### Getting a Wallet Trust Profile
+
+```
+Prompt: "What's the trust profile for vitalik.eth?"
+
+The agent will call get_wallet_trust_profile with:
+- wallet: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
+```
+
+### Batch Trust Profiling
+
+```
+Prompt: "Compare trust profiles for these 3 wallets: 0xd8dA..., 0xAb58..., 0x7a25..."
+
+The agent will call get_batch_wallet_trust_profiles with:
+- wallets: [{ wallet: "0xd8dA..." }, { wallet: "0xAb58..." }, { wallet: "0x7a25..." }]
+```
