fix: prevent floating windows from getting stuck in corner after workspace switch

When AeroSpace hides windows from inactive workspaces, it moves them to a
screen corner and saves their previous position so they can be restored later
(unhideFromCorner). A race condition with AX notifications could cause the
following broken cycle:

1. hideInCorner() saves the normal position, moves window to corner
2. unhideFromCorner() restores it, clears prevUnhiddenProportionalPosition
3. A spurious AX event triggers unhideFromCorner() again — no-op since
   prevUnhiddenProportionalPosition is already nil, window stays in place
4. Next workspace switch calls hideInCorner() again — isHiddenInCorner is
   false (nil check) — so it saves the *current* position, which is already
   the corner position
5. unhideFromCorner() then restores the window to the corner → stuck forever

Fix: in hideInCorner(), only record the window's position when its top-left
corner is actually inside the monitor's visible rect. If it's already outside
(stuck in a corner from a previous broken cycle), skip saving to avoid
permanently anchoring it to the corner.

Fixes: #1875
