Style Optimization: Adjust Document Comment Color & Ensure Function Parameter Color Consistency

1. The theme's current document comment color is too prominent, causing visual distraction. Could we adjust it to a moderate grayscale? It’ll blend better with the theme and reduce eye strain during long coding sessions.
2. Function parameters have different colors in declaration vs. usage. If this isn’t intentional, could we unify them? It’ll keep the theme consistent and make code easier to read.

As shown in the following figures, It is felt that VS Code's approach in these two aspects is more appropriate, which is for reference only.
