Connect CockroachDB to CrewAI

Expose KosmoKrator integrations to CrewAI workers as scoped local tools.

Wrap kosmo integrations:call for specific tasks or connect workers to a local MCP gateway. The gateway is local, scoped to this integration, and starts with --write=deny so CrewAI can inspect read-capable tools without receiving write access by default.

CockroachDB MCP Config for CrewAI

Use per-worker integration scopes to avoid giving every worker every tool.
