Summary

Bump the pinned Copilot CLI version from v1.0.20 to v1.0.21 to unblock Copilot-engine workflows.

Context

Two distinct failures are affecting Copilot-engine workflows (#25680):

Bug Version Failure Root Cause
A v1.0.22 (latest on Apr 9) Hangs indefinitely Memory backend unavailable in AWF sandbox (fixed in v1.0.23)
B v1.0.20 on v0.67.4 Silent crash (exitCode=1, 0B output) GITHUB_COPILOT_INTEGRATION_ID env var (fixed in v0.68.0)

v1.0.21 was the last confirmed working version (successful runs on Apr 9 before v1.0.22 rolled out).

Validation

Run the smoke-copilot workflow on this branch to verify v1.0.21 works with the v0.68.0 runtime.

Changes

  • pkg/constants/version_constants.go: 1.0.201.0.21
  • 123 lock files recompiled

Refs #25680

v1.0.20 crashes silently (exitCode=1, 0B output) in the v0.67.4+
runtime. v1.0.21 was the last confirmed working version before v1.0.22
introduced a startup hang (fixed in v1.0.23).

Pinning to v1.0.21 to unblock Copilot-engine workflows while we
validate whether v1.0.23 is safe for broader adoption.
