Add Hive Intelligence (remote server, finance)

[rishabhng]

Adds Hive Intelligence as a remote-type entry (modeled on servers/stripe-remote).

• Hosted streamable-HTTP MCP at https://mcp.hiveintelligence.xyz/mcp
• Live crypto market data: 607 tools (prices, on-chain, DeFi, derivatives, NFTs, token-security) with provenance receipts on every answer
• Reviewers can verify with zero credentials: the endpoint allows 25 calls/IP/day keyless (initialize + tools/list + hero tools work with no account)
• Accounts use OAuth 2.1 with API-key (Authorization: Bearer) fallback; no oauth provider block included since the server is usable without credentials — happy to wire one if preferred
• Published in the official MCP registry as xyz.hiveintelligence/mcp; public repo: https://github.com/hive-intel/hive-sdk

No container involved (remote type). Happy to adjust category/tags to house style.
