In `@Swift` Shift/src/Manager/WindowManager.swift:
- Around line 31-37: The getSize function ignores the Bool return value from
AXValueGetValue, which indicates whether the geometry extraction succeeded. If
the extraction fails, the function returns an NSSize with potentially invalid or
zero values instead of nil. Check the return value of AXValueGetValue and only
proceed to create and return the NSSize if the extraction was successful;
otherwise return nil. Apply the same fix to the getPosition method which has the
identical issue.
- Around line 21-29: The resize function can return false after successfully
moving the window origin but failing to set the size, causing callers like
MouseTracker to treat the operation as failed while the position has already
changed, leading to desynchronization. Fix this by reordering the operations to
set the size attribute first before moving the window origin, or implement
rollback logic to undo the origin move if the size operation fails. This ensures
the resize operation is atomic and either fully succeeds or fully fails without
partial side effects.

In `@Swift` Shift/src/Manager/WindowManager.swift:
- Around line 31-36: In the getSize function, replace the force cast `r as!
AXValue` with a safe cast pattern using `as?` to check if the CFTypeRef is
actually an AXValue before attempting to use it. If the cast fails (meaning r is
not an AXValue), return nil to avoid runtime crashes from invalid payloads. This
same safety hardening should also be applied to the similar force cast mentioned
around line 104-108 in another function.
- Line 93: In the getWindow(from:) function at line 93, replace the force-cast
operator `as!` with an optional cast operator `as?` when casting the parent
parameter p to AXUIElement. Then add appropriate error handling to gracefully
manage cases where the parent is not of the expected AXUIElement type, rather
than allowing a runtime crash during recursion. This ensures that unexpected
types from the Accessibility framework are handled safely instead of causing the
application to crash.

…checks - Use CFGetTypeID(r) == AXValueGetTypeID() instead of as? AXValue (which always succeeds on CF types and triggers a compiler warning/error) - Use CFGetTypeID(p) == AXUIElementGetTypeID() in getWindow(from:) - Check AXValueGetValue return value in getSize() and getPosition() - Add os_log error diagnostics for every failure path - Keep existing guard-let for AXValueCreate return values
