Tab switches slid in a fixed direction (and sometimes flipped between push/pop feel,
so the direction felt random). Now the slide follows the target tab's position in the
bottom bar: tapping a tab to the right slides in from the right, a tab to the left
slides in from the left — applied across all four enter/exit/popEnter/popExit
transitions so it's consistent regardless of how Compose classifies the move. Detail
screen push/pop transitions are unchanged.
