Changes

Text.tsx — Core implementation

• Added whiteSpace?: 'pre' | 'normal' | 'nowrap' | 'pre-wrap' | 'pre-line' to TextProps
• Destructured whiteSpace from props and passed it as a data-white-space attribute (consistent with the data-size / data-weight pattern)

Text.module.css — Styling

• Added 5 CSS rules scoped via :where([data-white-space='...']) selectors, one for each supported value

Text.test.tsx — Tests

• Added test asserting data-white-space attribute is set for each valid value
• Added test asserting the attribute is absent when the prop is omitted

Text.stories.tsx — Playground story (by you)

• Added whiteSpace: 'normal' to default args
• Added a whiteSpace radio control with all 5 options

Text.features.stories.tsx — Feature stories (by you)

• Added 5 individual stories: PreWhiteSpace, NormalWhiteSpace, NowrapWhiteSpace, PreWrapWhiteSpace, PreLineWhiteSpace

styled-react/Text.tsx — Styled wrapper (by you)

• Added whiteSpace to BaseTextProps to keep the styled variant in sync
