Instead of flattening the entire operation registry into individual
OpenAI tool definitions (with schema normalization headaches), the
AgentLoop provides the same 4 discovery+call meta-tools that the MCP
server already exposes: hub.list, hub.search, hub.schema, hub.call.
This eliminates operationToOpenAITool() + normalizeSchemaForOpenAI()
entirely. The LLM discovers and calls operations the same way an MCP
client does. Same tool defs in context always (4, not N), same call
protocol path (callMap.call()), unified interface for both MCP and
direct agent consumers.
