Do not merge. Bisection probe for the macOS VSD DispatchCache hang (dotnet/runtime#128955, #128859).

Rolls the dotnet/dotnet runtime + SDK dependencies (eng/Version.Details.xml, eng/Version.Details.props, global.json) back to a coherent older codeflow snapshot, and reverts #63531 so the PR-check macOS test leg runs on the OSX.15.Amd64.Open Helix queue (where the hang reproduces). Goal: find which runtime version bump introduced the hang. Tests will be run ~3x.
This probe: VMR 11.0.0-preview.5.26268.112 / SDK 11.0.100-preview.5.26227.104 (codeflow #66741, May 19).

@wtgodbe wtgodbe force-pushed the dotnet/runtime-bisect-p5-26268 branch 3 times, most recently from 373b155 to 0693b05 Compare June 16, 2026 19:55
…acOS VSD hang

Merge-downgrade of eng/Version.Details.{xml,props} + global.json to dotnet/dotnet
codeflow commit 2f91a9d (keeps arcade/Wix + main-only deps at main, no dep removal).
Reverts the macOS PR-check Helix queue (dotnet#63531) back to OSX.15.Amd64.Open so the
hang-prone queue is exercised. Rolls the 2 CertificateGeneration files back to the
target commit to stay coherent with the older runtime (pre-dotnet#66727 Process.Run API).

Draft probe PR for runtime mac-hang bisection. Not for merge.
