v0.8.1 - Steadicam

✨ New Features

CameraState.referenceUp - a shared "up" hint a Body can hand to a paired Aim, instead of every rotation-building Aim defaulting to a hardcoded world-up. Follow writes it, rotated the same way as its own offset (so it reflects whatever the current bindingMode derived), and HardLookAt/RotationComposer read it when building their look-at rotation. Body still never touches rotation and Aim still never touches position - referenceUp is just a value passed between them, interpolated during blends like every other CameraState field.

HardLockToTargetBody no longer pops on a retarget mid-blend - it published out.target as the raw, undamped target position while out.position was the damped one still catching up. BlendHints.cylindricalPosition/sphericalPosition derive an orbit offset from position - target, so retargeting mid-catch-up made that offset jump instantly, popping any blend that read it. Fixed by publishing out.target as an exact copy of the (already damped) out.position - HardLockToTargetBody has no persistent offset by definition, so this is always correct.
FollowBody had the same bug, fixed the same way in spirit - Follow has a real, persistent, non-zero offset though, so out.target is now derived algebraically from the damped position minus the rotated offset, keeping the offset BlendHints read always exactly what's configured, regardless of damping lag.

New interactive examples site - collection of live demos, each with a Leva control panel and a "spectator" inset watching the primary camera from outside.
Only a handful of pieces are covered so far - more scenes land incrementally.

math bumped from a canary prerelease to the first stable ^0.1.0 release.
New regression tests for both fixes above, each confirmed to fail against the pre-fix code before the fix landed.
