feat: Android Dialog Capture (#302)

## Summary

Implement capture multiple type of windows and draw them on each other. 
Some windows like Toast still not captured. Hoping in the next PRs

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Adds multi-window capture and compositing (activity + dialogs) with
per-window masking, refactors capture into `replay.capture`, and updates
instrumentation/internals accordingly.
> 
> - **Capture (refactor to
`com.launchdarkly.observability.replay.capture`)**:
> - **Multi-window capture & compositing**: New
`WindowInspector`/`WindowEntry` enumerate app windows and choose a base
window; captures overlays and composites bitmaps with position offsets.
> - **CaptureSource rewrite**: Uses `PixelCopy` (with fallback to canvas
draw), synchronizes to frame, applies masking, encodes WEBP -> Base64,
and emits `CaptureEvent`.
>   - Moves `CaptureEvent` to `replay.capture` package.
> - **Masking**:
> - `SensitiveAreasCollector.collectFromActivity` now collects from a
root `View` (not `Activity`), enabling per-window mask extraction.
> - **Instrumentation**:
> - `ReplayInstrumentation` integrates new `CaptureSource` API (no
Activity lifecycle attach), continues emitting media/interaction logs.
> - **Exporter/Tests**:
> - Update imports to `replay.capture.CaptureEvent`; minor
formatting/test adjustments.
