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.

 # Changelog
 
+## 1.1.2 — 2026-07-14
+
+Third integration-feedback release — a general action button, responsive
+faders everywhere, and the label-scaling gap, all surfaced building a
+resizable streaming studio.
+
+### New components
+- `Button` — a normal **click-to-fire** command button in the panel style
+  (Regenerate, Add, Apply, Refresh), the non-latching sibling of `PushButton`.
+  It's `PushButton` locked to the new `mode="action"`: never latches, shows a
+  press-down + a brief LED flash, calls `onClick`. `led="dot"` (default) gives
+  the corner-dot look; `led={false}` a plain button.
+
+### Buttons
+- `PushButton` gains **`mode="action"`** (alongside `toggle`/`momentary`) and
+  an `onClick` prop — the stateless command-button behavior `Button` wraps.
+
+### Responsive faders
+- **`fill`** on `LEDFader` (matching `Fader`) — the fader stretches along its
+  travel axis to fill the container instead of a fixed `length`, so faders in
+  resizable dock panels size themselves with no wrapper measurement.
+
+### Label scaling
+- **`labelSize`** on `IndicatorLamp` — the caption otherwise tracks `size` but
+  is floored at 10px; set this to shrink it with a small lamp (e.g. matching a
+  dense header row). Also on `LampRow` for parity.
+
+### Docs
+- A dedicated **Buttons & switches** section with a "which do I use?" guide
+  (Button = action · PushButton = latch · TransportButton = transport ·
+  ToggleSwitch = boolean · SegmentSwitch = mode) and a live demo of each.
