fix(runtime): immediateRender for set tweens + array timeline normalization (#1692)

* chore(studio): remove all console.* calls from studio package

* chore(studio): address review — remove dead stubs, restore consent notice

- Delete empty if-blocks left after console removal (snapTargetCollection,
  Player asset-poll, useTimelineSyncCallbacks 5s probe, useGestureRecording
  dev guard + now-unused isDevBuild) and the stale "surface in dev" comment.
- Drop the dangling no-console pragma + dead duplicate-id branch in sourcePatcher.
- Restore the one-time telemetry consent disclosure in showNoticeOnce (kept
  behind a pragma — it is a user-facing notice, not debug noise).
- Remove the missed timelineIcons console.warn while preserving the
  `tag || "div"` null-safety fallback.
- Route caption auto-save failures (a data-loss path) through telemetry
  instead of swallowing silently.
- Restore the accidentally-clobbered css-var-fonts output.mp4 fixture.

* fix(runtime): immediateRender for set tweens + array timeline normalization

- Set tweens now emit immediateRender:true so they render on page load
  without requiring the runtime to seek past position 0
- Runtime IIFE normalizes array timelines (window.__timelines = [tl])
  to keyed objects, and auto-adds data-start on root elements
- Drag teardown clears translate:none to prevent #1673 fly-off
- Position-only set tweens hidden from timeline diamonds (3 cache paths)
- Parser: ease-only keyframe update preserves existing properties

* fix(runtime): address review — restore perf gate, debug surface, scrub restore

- Restore the #1651 skipForInjectedVideo gate in media.ts that was dropped on
  restack — avoids ~2400 wasted per-tick seeks on video-heavy renders.
- Restore the console.debug body + docstring bullet of swallow() in
  diagnostics.ts: the __hfDebug opt-in debug surface had been gutted to an
  empty if-block.
- Rebind: after the progress-cycle set() kick, seek to state.currentTime via
  totalTime() instead of snapping to 0, so a rebind after scrub / soft-reload
  restore keeps the playhead.
- Array __timelines normalization + data-start default now resolve the root
  via a shared findRootCompositionEl() that honors data-root="true" first
  (matches resolveRootCompositionElement, which now delegates to it).
- Ease-only keyframe update leaves a primitive (non-object) keyframe value
  untouched instead of wiping it to {}; add a preservation unit test.
- Document the boundDuration<=0 progress(1) kick + restore the STATIC-case
  comment in gsapRuntimeBridge.
