Re-review in progress. One new consistency issue flagged.

• Update Roo Code Router overview frontmatter description (still says “Roo Code Cloud”).
• Update v3.25.18 release notes step to select “Roo Code Router” (still says “Roo Code Cloud”).
• docs/credits/overview.md frontmatter description still refers to “Roo Code Cloud” (should be Router, or describe credits directly).
