Subject: [PATCH] fix(installer): disable single-file compression to prevent
 WPF startup AV
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Published installer was crashing at launch with 0xc0000005 (access violation)
and exit code 0x80131506 (COR_E_EXECUTIONENGINE), faulting inside the exe's
own bundle-extractor bootstrap before any managed code ran. This is a known
interaction between WPF, single-file publish, and EnableCompressionInSingleFile.

Disable compression (exe grows ~30% but startup becomes reliable).
IncludeAllContentForSelfExtract stays true — WPF still needs on-disk
extraction for XAML resources.
