Add cache hint fields to list and resource-read protocol result models with conservative defaults of ttlMs=0 and cacheScope=public. Cover default serialization, explicit hints, validation, low-level wire behavior, high-level MCPServer defaults, and migration notes without adding new high-level server configuration API.

Summary
Implements SEP-2549 cache hints for Python SDK protocol result models.
Adds
ttlMsandcacheScopesupport to:ListToolsResultListPromptsResultListResourcesResultListResourceTemplatesResultReadResourceResultThe SDK defaults to
ttlMs=0andcacheScope="public"so existing Python code constructing these models remains usable while serialized responses include the new cache hint fields. Older server responses that omit the fields also parse with those defaults.This PR does not implement client-side caching, cache invalidation logic, or new high-level
MCPServercache configuration APIs.Fixes #2802.
