⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

Breaking Change Analysis

Result: No breaking changes detected

Reasoning: This PR only modifies the help text for the --aliases CLI argument. The changes are purely documentation improvements to make the help text clearer - explaining that the schema field becomes the Pydantic alias, and providing more concrete examples. No actual functionality, code generation output, API, CLI behavior, or default values were changed. This is a documentation-only change that doesn't affect any existing users or their workflows.
