fix: make tool-calling-with-thought-signatures test resilient to message ordering

The test was failing on Windows CI because streaming messages (text chunks,
toolCallPrepare, usage) can arrive in slightly different order due to
platform-specific timing/buffering differences.

- Add `consume-contents` helper to batch-consume notifications
- Use `m/in-any-order` matcher for streaming messages where order may vary
- Keep strict ordering for deterministic parts (reasoning flow, tool execution)
