fix: drag-to-transfer drop not triggering transfer dialog

s_dropTargetIdx was reset to -1 unconditionally each frame, including
the release frame. Since drop target detection runs in PASS 2 (after
the drop handler), the target was always -1 when checked. Only reset
while mouse button is held so the previous frame's value is preserved.

Also bump version to 1.2.0-rc1 and add release notes.
