Crashpad uploads minidumps straight to the DSN's /minidump endpoint,
which our tracker does not implement — every native Windows crash
(e.g. faults inside libmpv threads, #1490) was silently dropped.
The inproc handler stackwalks at crash time and reports through the
regular envelope endpoint, and crashpad_handler.exe/crashpad_wer.dll
leave the bundle.
