v1.1.2: action button, responsive faders, label scaling

Third integration-feedback release from building the streaming studio.

- New `Button` — a click-to-fire command button in the panel style, the
  non-latching sibling of PushButton. Implemented as PushButton's new
  `mode="action"` (never latches, press-down + brief LED flash, `onClick`);
  led="dot" (default) matches the corner-dot look, led={false} is plain.
- `fill` on LEDFader (parity with Fader) — faders stretch to fill their
  container in resizable panels instead of a fixed pixel length.
- `labelSize` on IndicatorLamp (and LampRow) — shrink the caption below its
  10px floor to match dense header rows.
- Docs: a dedicated "Buttons & switches" section with a decision guide
  (Button/PushButton/TransportButton/ToggleSwitch/SegmentSwitch) + live demos.

Library + docs typecheck and build; 38 tests pass.
