Build Status

Note: The make recompile step could not complete due to Go 1.25.0 download restrictions in the CI environment. The constants have been updated in pkg/constants/constants.go (lines 307 and 312), but workflow lock files were not regenerated.

Required Action: The make recompile command must be run in a development environment with access to Go 1.25.0 to regenerate workflow lock files before deployment.

Changes Made:

- const DefaultClaudeCodeVersion Version = "2.1.39"
+ const DefaultClaudeCodeVersion Version = "2.1.42"

- const DefaultCopilotVersion Version = "0.0.409"
+ const DefaultCopilotVersion Version = "0.0.410"
