fix(button): keep intrinsic labels on one line

[hyochan]

Summary

• Keep string command labels on one line during Android intrinsic layout measurement; custom element labels retain their own layout.
• Cover solid and outlined labels through press and loading, and add an intrinsic solid-label Storybook case.

Verification

• Full test:all: 23 suites, 304 tests; lint, types, component and story coverage pass.
• Package build and Storybook production build pass.
• Physical Pixel 10: fresh local BooKoo 1.0.1 QA APK with embedded JS; full Add entry label centered at idle, held, and after navigating back.
• Physical iPad mini: CTA opens the editor and remains complete after returning.
• Live web Light/Dark solid and Dark outlined stories inspected; dark solid press preserves its label.

No npm publication in this PR. The consumer carries only compiled output while explicit prerelease publication approval is pending.

Summary by CodeRabbit

• Bug Fixes
  • Button labels now remain on a single line during intrinsic-width sizing, including solid and outlined button styles.
  • Loading buttons with text now preserve consistent single-line label rendering.
• Documentation
  • Added a Storybook example for medium-sized solid intrinsic-label buttons.
