feat: add breadcrumb & meter components, and expanded utilities

Hi! This PR adds several missing components and utilities to the library, following the existing minimal, semantic, and class-free philosophy.

Summary of Changes

• New Breadcrumb Component: Uses a semantic nav structure (no extra classes required) based on aria-label="Breadcrumb".
• New Meter Component: Cross-browser styled <meter> element using the library's design tokens (--success, --warning, --danger).
• Expanded Utilities:
  • Added .sr-only (accessibility), .truncate (text-overflow), and .border.
  • Added .rounded and .rounded-full border-radius helpers.
  • Added background helpers (.bg-secondary, .bg-faint).
  • Added a full padding scale (.p-0 through .p-6).
  • Added basic print styles (.no-print, background normalization).
• Grid Layout: Introduced a tablet breakpoint at 1024px for better responsive control.
• Documentation: Updated utilities.md and breadcrumb.md to reflect the new additions.

Design/Code Style

• All CSS follows the project's signature compact one-liner style.
• Components were designed to be "zero-class" where possible, relying on semantic HTML.
• Rebuilt with make dist and verified across platforms.

Everything was tested in the latest version to ensure zero regression for existing layouts.

This is a bunch of random changes, which don't make sense to me, unfortunately.
