fix(catalog): keep the text stagger preview inside the frame

[AksharP5]

What

The Text Stagger Catalog preview clips the first and last words at opposite frame edges. This keeps the complete phrase visible throughout playback.

Fixes #3253.

Why

The 2.6× wrapper scale made the demo wider than its 1920×1080 composition. The small label also had only 2.46:1 contrast against the background.

How

Reduced the preview-only wrapper scale to 1.9×, changed the label to a compliant gray, and regenerated the Catalog payload. The installable component and animation timing are unchanged.

Test plan

• Unit tests added/updated
• Manual testing performed
• Documentation updated (generated Catalog payload)

Validated with:

• bun run build
• bunx oxfmt --check registry/components/text-stagger/demo.html
• bun run lint:registry-items text-stagger
• npx hyperframes check against the standalone demo
• Before and after Catalog renders inspected

Fact-checked against the live production Catalog at hyperframes.heygen.com and rendered production vs this exact head side-by-side at the same 1920×1080 viewport and settled playback state. The reported clipping/positioning defect is real, and this preview-only change fixes it without touching the installable component or animation timeline. The generated Catalog payload matches the demo source. Approved.

Fresh exact-head approval after the restack. Fact-checked the live production Catalog and rendered production vs this head side-by-side at the same 1920×1080 viewport and settled playback state. The reported defect is real and this preview-only change fixes it without altering the installable component or timeline. Regenerated payload is source-identical (ignoring terminal newline); registry-item lint passes.
