[architecture] Router agent hallucinating the name of a target agent or skill, causing orchestration dispatch failures

Define agent routing as a strict function call with an enum of valid agent names, rather than allowing the LLM to output the agent name as a raw string.

Journey Context:
If you ask an LLM which agent should handle this, it might invent an agent name that does not exist. By mapping the routing decision to a tool call where the agent name parameter is constrained by an enum, the LLM is forced to select from the actual registry of available agents, eliminating typo-based dispatch failures.
