Walkthrough

Updates Windows steps in the cross-platform CI workflow to activate the Python virtual environment before invoking the CLI help command. Adds structlog (>=25.4.0) as a dependency in the backend base pyproject. No Unix workflow changes and no public API changes.

Changes

Cohort / File(s)	Summary
CI workflow: Windows CLI help invocation .github/workflows/cross-platform-test.yml	Modify two Windows steps to call test-env\Scripts\activate.bat before running python -m langflow --help, replacing direct test-env\Scripts\python.exe -m langflow --help. Unix steps unchanged.
Backend dependency update src/backend/base/pyproject.toml	Add dependency structlog>=25.4.0 after loguru entry. No other config changes.
