Patch Changes

• #10106 9f30267 Thanks @hntrl! - Add package version metadata to runnable traces. Each package now stamps its version in this.metadata.versions at construction time, making version info available in LangSmith trace metadata.

• #10152 e0e5a02 Thanks @hntrl! - fix(google-common): preserve anthropic tool_use blocks and avoid duplicates in Claude Vertex formatting

  Improve Anthropic message conversion in the Vertex Claude path by preserving tool_use blocks from assistant content and deduplicating tool_use entries when they also appear in tool_calls.

  Add regression tests for Anthropic formatting with multi-turn/tool message flows.
