Add a 'size' attribute to the chip component with two values: - 'normal' (default, undefined): 32px height (existing behavior) - 'small': 24px height using controlSlimHeight token This is a non-breaking change. Existing chips without a size attribute continue to render at 32px. Changes: - Add ChipSize enum to chip/types.ts - Add size attribute to Chip class - Add sizeBehavior utility (mirrors appearanceBehavior pattern) - Update styles with controlSlimHeight for small variant - Add unit tests for size attribute - Update Storybook stories and matrix with size states - Update Angular directive with size property and tests

@fredvisser sizing is done via css and not attributes. Controls should respond to sizing via css. See spinner sizing docs as an example: https://nimble.ni.dev/storybook/index.html?path=/docs/components-spinner--docs&globals=backgrounds.grid:!true

Gotcha - refactored to document the CSS approach like we do with the spinner 👍

Rationale
The
nimble-chipcomponent needed documentation for how to achieve the 24px compact size variant. Per design guidance, sizing should be done via CSS rather than component attributes, following the same pattern as the spinner component.Implementation
Added CSS-based sizing documentation and a Storybook size control:
sizecontrol under the Styles category with "Default (32px)" and "Small (24px)" radio options. Selecting "Small" appliesheight: var(--ni-nimble-control-slim-height)via inline CSS, matching the spinner approach.control-slim-heightdesign token.No component code changes — sizing is purely a consumer-side CSS override using existing design tokens.
Testing
No new component tests needed since no component code was changed. The sizing control is visible in Storybook.
