Subject: [PATCH] Update Microsoft.Diagnostics.Runtime to 4.0.722401
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update ClrMD to the first stable release with cross-bitness address
truncation fixes (microsoft/clrmd#1423). This version correctly handles
sign-extended CLRDATA_ADDRESS values on 32-bit targets, enabling
32-bit hosts to read 64-bit dumps.

Remove the cross-bitness dump test skip added in #127118 — ClrMD now
supports this scenario.
