Stopping a debugger no longer reports success when inherited output
streams stay open, so BinarySession cannot reopen a binary a child is
still changing. Concurrent Cutter cleanup retries share one receipt
acknowledgement instead of treating a consumed receipt as failure.

* fix(windows): resolve selected provider paths absolutely

* fix(gdb): report decoding loss in failed startup evidence

* fix(rizin): scope decoding loss to collected command frames

* test(mcp): cover snapshot retirement in reverse tools CI
