v1.0.2

Fixes

• Theming on Angular Material 17+: migrated every button design token from the
  legacy --mdc-*-button-* names to the current --mat-button-* names — label and
  container colors, outline color, container shape (border-radius) and elevation
  shadow. Material no longer emits the --mdc-* tokens, so the directive previously
  fell through to its --mat-sys-* fallbacks and ignored any button-level
  customization coming from the Angular Material theme (e.g. mat.button-overrides(...)).
  The --split-button-* overrides and --mat-sys-* defaults are unaffected.
• Auto-adapt inside a mat-toolbar: the transparent variants (text, outlined)
  now fall back to --mat-toolbar-container-text-color, so their label and chevron
  pick up the toolbar's text color automatically — matching how a real matButton
  behaves. The container variants (filled, tonal, elevated) are unchanged (they keep
  their own label color over their own background).

Docs

• README and demo documentation now describe the toolbar auto-adaptation behavior.
• Demo playground gains a contrasted mat-toolbar example (the split-button's label
  follows the toolbar text color) and carousel pickers for the variant and Material
  palette selectors.

Chore

• Updated the dev/build toolchain to patched releases (Angular 21.2.x, Angular CDK/Material
  21.2.14) and pinned undici/@babel/core via npm overrides, clearing all high/moderate
  npm audit advisories. These are devDependencies only — the published package is unaffected
  (it ships nothing but tslib at runtime).
