feat(studio): marquee selection, AE presets, per-keyframe ease + velocity fitting

Marquee selection: click+drag on empty canvas draws a dashed selection
rectangle. All elements whose OBB intersects are group-selected via
SAT. Shift+marquee adds to selection. Click on empty deselects.

Per-keyframe easing: each keyframe segment has its own ease, editable
via expandable bezier curve editor in the Animation panel. Parser
preserves per-keyframe ease through round-trips (ease-only updates
preserve existing properties).

AE Easy Ease presets: correct After Effects bezier values (0.333, 0,
0.667, 1) in the preset grid.

Velocity-based curve fitting: gesture recordings analyze velocity
profile and assign per-keyframe custom eases automatically.

Gesture smoothing: Gaussian-weighted moving average (from PR #1658)
+ easeEach support for keyframed tweens + fetch-cancellation race
fix in useGsapAnimationsForElement.

+  description="Released - 2026-06-24"
+  tags={["Release", "Producer", "Core", "Studio"]}
+>
+This stable release improves render reliability and skill authoring: producer duration
+now falls back to sub-composition timing, empty sub-composition files no longer abort
+renders, and Studio timeline styling handles missing tags safely. It also ships
+music-to-video workflow updates, per-skill telemetry, and clearer CLI install/debug
+guidance.
+
+## Features
+
+- **CLI:** Per-skill usage telemetry ([4961e4e4](https://github.com/heygen-com/hyperframes/commit/4961e4e4770a9b38eb34fef957c0ac8764614ce8))
