cache hints and x-mcp-header input designation

  • createApp({ cacheHints }) and a per-resource cacheHint set ttlMs / cacheScope on the 2026-07-28 cacheable results (#359)
  • headerParam(schema, 'Name') mirrors a tool input property onto an Mcp-Param-Name request header; an illegal placement is rejected at definition time and by the new header-param-designation lint rule (#360)
  • transport.sessionMode advertises the resolved mode instead of the configured auto, and narrows to 'stateful' | 'stateless' (#357)
  • Shipped skills: add-resource 1.5, add-tool 2.20, api-config 1.12, api-linter 1.12
  • deps: openai ^7.4.0 → ^7.5.0 (dev)
