fix(studio): keyframe bug fixes — gate delete hooks, fix value corruption, gesture recording (#1314)

- Gate stripStudioEditsFromTarget/bakeVisibilityOnDelete behind a
  stripStudioEdits flag on the delete mutation type so they only fire on
  user-initiated deletes, not on internal delete-then-recreate drags.

- Add bakeVisibilityOnDelete to the remove-all-keyframes handler so
  elements with CSS opacity:0 stay visible after collapsing keyframes.

- Fix integer rounding in readAllAnimatedProperties: use 3-decimal
  precision for visual properties (opacity, scale, rotation) instead of
  Math.round which corrupted mid-fade values to 0.

- Guard VISUAL_BASELINE against cross-tween contamination by querying
  __timelines for properties animated by other tweens on the same element.

- Harden bakeVisibilityOnDelete: reverse-scan keyframes for the last one
  containing opacity, guard against relative values (+=/-=/*=), and add
  Number.isFinite check.

- Fix falsy-zero doubling in drag commit: replace || fallback with
  Number.isFinite so a base GSAP position of 0 is correctly preserved.

- Fix gesture recording sign inversion: remove pointerElementOffset
  subtraction from dx/dy formula and instead apply it once to basePosition
  so the element center tracks the pointer.

- Fix TypeScript build errors in gsapSoftReload.ts (6 double-casts).

- Strip all diagnostic logs from production code.
