Why

The intro listed "compile-time checks, tests and diffs", but the third point of "Verify early, test properly, and refactor safely" is refactoring, and safe renames are what set SQLBuild apart.

Changes

• Homepage hero and README: "SQLBuild brings compile-time checks, tests and safe renames to your SQL, so change stops being risky."
• Docs home: "diffs" becomes "safe renames"; its ending is unchanged.
• Homepage content width goes from 1140px to 1240px and the hero paragraph cap from 62 to 68 characters, so the longer sentence stays on two lines on typical desktop widths.
• Regenerated the bundled skill reference for the docs home.

Verification

• Rendered the homepage at 1356px and 1600px: the hero paragraph is two lines, and no code block overflows anywhere on the page.
• Smaller screens are unchanged, because the width already follows the window below 1240px.
