`Anthropic TypeScript SDK` `v0.97.1` Fixes `SessionToolRunner` Tool-Call Ownership

A narrow runner bug fix prevents SessionToolRunner from handling tool calls it does not own. Upgrade only if your agent flow uses SDK-managed tool sessions.

[ KEY POINTS ]
  1. Release date is 2026-05-19. Scope is a patch update from sdk-v0.97.0 to sdk-v0.97.1, not a model or pricing change.
  2. The only listed fix is runner: skip tool calls SessionToolRunner does not own; relevant to multi-tool or session-based agent loops.
  3. No new API surface is mentioned. If your integration does not use SessionToolRunner, there is little urgency.
