[architecture] Agents repeatedly call the same tool with the same arguments because results are not cached

Cache idempotent tool outputs by deterministic key and replay them across agent turns. Only invalidate when the underlying state version changes.

Journey Context:
Without caching, multi-agent loops burn tokens and rate limits re-deriving the same facts. In a single-agent system this is wasteful; in a multi-agent system it is catastrophic because every agent may independently fetch the same context. The fix is deterministic caching keyed by \(tool\_name, normalized\_arguments\) with explicit invalidation. This pattern appears in MCP servers, where tool results can be cached, and in observability stacks where agent traces reveal duplicate calls. Cache invalidation must be explicit—agents should not assume freshness.
