Summary of Changes

Hello @ai-easy-cpu, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a minor but important documentation inaccuracy within the profiler.py module. It specifically rectifies a help message associated with a boolean command-line argument, ensuring that users receive precise information regarding its function. This change improves the clarity and usability of the profiling tool by providing correct guidance on its parameters.

Highlights

• Documentation Correction: Corrected a misleading description for a command-line argument in python/sglang/profiler.py.
• Argument Clarity: The help text for a boolean argument was updated to accurately reflect its purpose: profiling prefill and decode separately, rather than incorrectly describing the number of forward steps.
