Update Hive Intelligence listing

[rishabhng]

Updates the Hive Intelligence entry to point at the maintained public hive-sdk repository and current hosted MCP/stdio/SDK/skills positioning instead of the stale hive-crypto-mcp link.

Maintainer note: this is a narrow refresh to keep Hive pointed at the maintained public repo (hive-intel/hive-sdk) instead of older Hive crypto MCP naming. Hive is positioned as a managed crypto intelligence MCP rather than another raw endpoint wrapper, so it should fit the broader blockchain MCP list without duplicating chain-specific entries.

Small supporting datapoint for this refresh: the hive-intel/hive-sdk surface this PR points to is now the one published in the official MCP registry (xyz.hiveintelligence/mcp), so the list row would match the same canonical repo and endpoint the registry verifies. No other changes on my side — glad to tweak the row format if you'd like.
