Disconnect weak signal dispatch through Qt's opaque connection handle instead of retaining a sender SignalInstance until receiver destruction. This prevents a deleted asynchronous startup operation from causing a deterministic PySide6 access violation during application shutdown.
Add a child-process regression that destroys many senders before their shared receiver and verifies normal process termination.

Retain asynchronous dialogs only while visible, use receiver-aware weak
signal dispatch for transient editors, and release registries on native
destruction. Add native and packaged lifetime probes that distinguish
live-wrapper growth from unavailable binding diagnostics.
