Pressing F computes the combined bounding box of every selected actor,
then animates the camera over 0.25s (smoothstep ease) to a distance that
fits the box in view while keeping the current viewing direction. The
orbit focal point and distance are synced so a subsequent Alt+drag
pivots around the new center.
No-ops cleanly when nothing is selected. Falls back to actor pivots
when no component reports valid bounds, and clamps the radius to a
minimum so point-like actors don't pull the camera onto them.
