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

[douglasborthwick-crypto]

Description

Adds a new InsumerAPI action provider for privacy-preserving on-chain wallet verification and trust profiling. InsumerAPI returns ECDSA-signed boolean attestations (pass/fail) rather than raw balances, so agents can verify wallet state without exposing holdings.

The provider is walletless (API-only, no wallet connection required) and supports 30 EVM chains + Solana + XRPL (32 total) through a single API.

Actions — 5 total

Action	Description
verify_wallet	Check if a wallet meets conditions (token balance, NFT ownership, EAS attestation, etc.). Returns a signed boolean attestation.
get_wallet_trust_profile	Get a multi-dimensional trust profile (17 checks across activity, assets, identity, compliance).
get_batch_wallet_trust_profiles	Batch trust profiles for up to 10 wallets.
validate_discount_code	Validate an INSR-XXXXX discount code (free, no auth).
list_compliance_templates	List available compliance templates like Coinbase KYC and Gitcoin Passport (free, no auth).

Tests

Unit tests: 21 tests covering all 5 actions, error handling, and network support. All passing.

pnpm jest --testPathPattern=insumer

PASS  src/action-providers/insumer/insumerActionProvider.test.ts
  InsumerActionProvider
    ✓ should have correct name
    ✓ supportsNetwork should return true for any network
    verify_wallet
      ✓ should successfully verify a wallet
      ✓ should handle API errors
      ✓ should handle network errors
      ...
  21 tests passed

Chatbot testing: This provider works with any of the example chatbots (e.g. typescript/examples/langchain-cdp-chatbot). Since it is walletless, no wallet funding or network setup is needed — only an InsumerAPI key (free tier available at insumermodel.com).

Chatbot: typescript/examples/langchain-cdp-chatbot
Network: any (walletless provider)
Setup: INSUMER_API_KEY env var set

Prompt: Check if 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 holds at least 1 ETH on Ethereum

Expected: Agent calls verify_wallet with the wallet address, chainId 1, 
and a token_balance condition for native ETH >= 1, then returns 
the pass/fail attestation result.

Prompt: Get the trust profile for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

Expected: Agent calls get_wallet_trust_profile and returns the 
dimensional trust scores (activity, assets, identity, compliance).

Prompt: What compliance templates are available?

Expected: Agent calls list_compliance_templates and returns the 
list of templates (e.g. Coinbase KYC, Gitcoin Passport).

Hey @phdargen — this has been waiting on review for a couple weeks. The one approval from Jeddyvgf was rejected by Heimdall (MFA issue). Would you be able to take a look? CI is green, PR is rebased and clean. Thanks!

@CarsonRoscoe @0xRAG — this PR has been open 17 days. CI green, just rebased. The one approval (Jeddyvgf) was rejected by Heimdall MFA. phdargen was tagged 3 days ago, no response. Would appreciate a review when you get a chance.
