caching

A server stamps CacheableResult hints (ttl_ms, cache_scope) onto list and read responses; a client honours them to skip redundant round-trips. The story will show per-result overrides on @mcp.resource() / @mcp.tool() and the client-side cache hit/miss path.

Status: not yet implemented. Server-side stamping landed (defaults ttl_ms=0, cache_scope="private"), but the per-result override hook and the client honouring path are not implemented yet. An example today could only show the defaults being emitted, not acted on.
