Add frame settings to wrap QR codes with decorative labels

[LGLabGreg]

Summary

This PR adds support for decorative frames with call-to-action labels around QR codes. Users can now wrap their QR codes in styled frames with customizable text, colors, and fonts using the new frameSettings prop.

Key Changes

• New FrameSettings type and prop: Added frameSettings to ReactQRCodeProps with support for 5 frame styles: banner-bottom, banner-top, ticket, bubble, and border
• Frame component: Created FrameBack and FrameLabel components to render frame backgrounds and labels with style-specific geometry
• Frame layout utilities: Implemented getFrameLayout() function to calculate frame dimensions, positioning, and quiet zones based on QR code size and frame style
• Download support: Updated raster and SVG download functions to handle non-square frames by scaling height based on viewBox aspect ratio
• Comprehensive tests: Added 16 test cases covering all frame styles, label rendering, color customization, and layout calculations
• Documentation: Added FrameSettings API reference page, frame examples with code blocks, and updated navigation/sitemap
• Demo interface: Created frame settings demo component for the interactive playground

Implementation Details

• Frames automatically add a minimum 2-module quiet zone around the QR code to ensure scannability on dark backgrounds
• The size prop applies to frame width; height grows to accommodate the label
• Long labels are automatically condensed to fit within the frame width using SVG textLength and lengthAdjust attributes
• Each ticket-style frame gets a unique mask ID to avoid conflicts when multiple QR codes are rendered
• Frame colors default to black; text color defaults to white on filled frames and matches frame color on outlined frames
• Empty label text (text: '') renders a square frame without label or divider elements

Walkthrough

The package adds configurable QR-code frames with five styles, calculated frame geometry, and frame-aware SVG and raster downloads. The documentation site adds frame settings references, examples, navigation, and interactive demo controls.

Changes

QR Code Frames

Layer / File(s)	Summary
Frame settings and geometry packages/react-qr-code/src/types/lib.ts, packages/react-qr-code/src/constants.ts, packages/react-qr-code/src/utils/frame.ts, packages/react-qr-code/src/utils/frame.test.ts	Adds FrameStyle and FrameSettings, frame defaults, and layout calculations for frame dimensions, labels, QR positions, and quiet zones. Tests cover layouts for the five styles, labeled and unlabeled frames, and scaling.
Frame rendering and QR integration packages/react-qr-code/src/components/frame.tsx, packages/react-qr-code/src/hooks/use-ids.tsx, packages/react-qr-code/src/react-qr-code.tsx, packages/react-qr-code/src/react-qr-code.test.tsx	ReactQRCode uses frame layout to render frame backgrounds, labels, and the QR code in an adjusted SVG viewBox. Tests cover frame styles, colors, labels, panel backgrounds, positioning, and unique ticket masks.
Frame-aware download sizing packages/react-qr-code/src/types/utils.ts, packages/react-qr-code/src/react-qr-code.tsx, packages/react-qr-code/src/utils/download.ts, packages/react-qr-code/src/utils/download.test.ts	Downloads use the SVG viewBox aspect ratio to determine image height. Raster downloads also use frame layout and QR offsets when drawing the QR code and positioning logos. Tests cover aspect-ratio sizing.
Frame documentation and demo controls apps/docs/src/components/demo/*, apps/docs/src/components/demos/frame.tsx, apps/docs/src/app/frame-settings/page.tsx, apps/docs/src/app/examples/frame/page.tsx, apps/docs/src/app/react-qr-code-props/page.tsx, apps/docs/src/config/navigation.ts, apps/docs/src/app/sitemap.ts, apps/docs/src/components/prop-type-tag.tsx, apps/docs/src/types/props.ts, apps/docs/public/llms*.txt, README.md, packages/react-qr-code/README.md, .changeset/qr-code-frames.md	Adds frame settings and example pages, interactive controls and rendered examples. Updates navigation, sitemap, prop references, feature lists, and the package changeset.

_{A rabbit draws a frame around the code,
Five styles make a tidy road.
“Scan me!” rests beneath the square,
The quiet zone stays roomy there.
I hop away; the scans are clear!}
