Add Chain 89001 (JAMIROQU.AI / INSAN) RPCs to extraRpcs.js

[CAPITALEXCHANGE]

Adds two public RPC endpoints for Chain 89001 — JAMIROQU.AI / INSAN, a sovereign EVM chain registered at ethereum-lists/chains/eip155-89001.

The chain is already listed at chainid.network/chain/89001 and chainlist.org/chain/89001, but the RPC list on chainlist.org is currently empty since extraRpcs.js doesn't have an entry yet. This PR fixes that.

Endpoints added

• https://rpc.jamiroqu.ai — primary
• https://rpc.capitalexchange.digital — secondary

Both RPCs run directly on the chain's two validator nodes; there is no third-party RPC provider involved.

Required questions

Service provider website: https://www.jamiroqu.ai

Privacy policy: We do not actively profile or store user data. IP addresses may be temporarily visible in operational logs for incident response and DDoS mitigation, and only consulted on user request for support. The RPCs operate as public, unauthenticated endpoints maintained by the chain operator (Capital Exchange Markets, Netherlands) - 2026.

Self-hosted / decentralised? Self-hosted by the chain operator on two independent validator nodes at this point in two jurisdictions (NL and DE). No third-party provider.

Verification

Both endpoints respond to standard JSON-RPC and report Chain ID 89001:

​bash
curl -s -X POST https://rpc.jamiroqu.ai
-H 'Content-Type: application/json'
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

{"jsonrpc":"2.0","id":1,"result":"0x15ba9"}
​0x15ba9 = 89001
