Add Hive Intelligence MCP catalog entry

[rishabhng]

Adds Hive Intelligence as a remote MCP catalog entry for Obot users who need production crypto market and on-chain intelligence from a single hosted endpoint.

What changed:

• Added hive_intelligence.yaml with the official Streamable HTTP endpoint: https://mcp.hiveintelligence.xyz/mcp
• Configured the required Authorization header with the Bearer prefix so users can provide their Hive API key at install time
• Included preview tools for Hive's discovery-first MCP workflow: search_tools, get_api_endpoint_schema, and invoke_api_endpoint
• Added the new YAML file to the tool-preview refresh workflow choices

Why this fits the catalog:
Hive Intelligence gives agents one governed MCP surface for live crypto prices, token and contract data, wallet/portfolio intelligence, DeFi analytics, DEX flows, NFT data, Solana data, network infrastructure, token risk/security checks, and prediction markets. The root MCP server keeps the initial tool surface compact while allowing runtime discovery of the provider-backed endpoints an agent needs for a specific market, wallet, protocol, or risk workflow.

Validation:

• Parsed hive_intelligence.yaml locally with PyYAML
• Parsed .github/workflows/tool-preview-refresh.yml locally with PyYAML

Following up in case it helps review: since submitting, Hive's listing went live in the official MCP registry as xyz.hiveintelligence/mcp (same remote endpoint as this catalog entry), so the server metadata here can be cross-checked against the registry record. The generate-matrix check is green and the branch has no conflicts. Happy to adjust naming or category if you'd like it shaped differently.
