- try_reembed() now handles same-HWND reparent scenario (mstsc reconnect resets parent)
- is_embedded() checks GetParent(hwnd) == parent_hwnd every 500ms
- _monitor_tick() two-stage: is_alive() for process death, is_embedded() for window loss
- build.py auto-cleans old releases (keep first + last 5)
- Cleaned old releases from git
