refactor(threat-detection): extract shared external detector WorkflowData setup into helper

[Copilot]

The synthetic WorkflowData construction for the external-detector path was duplicated verbatim across buildInstallDetectionEngineForExternalDetectorStep and buildExternalDetectorExecutionStep, making env/APITarget propagation logic a divergence risk.

Changes

• threat_detection_helpers.go — New buildExternalDetectorWorkflowData(data, engineID) helper centralizes the shared setup:

  • Base detection context via buildThreatDetectionWorkflowData
  • Tools = {"bash": ["*"]}
  • Engine config clone/reuse via canReuseThreatDetectionEngineConfigForExternalDetector
  • Env merge via mergeThreatDetectionEngineEnv
  • APITarget inheritance from main engine config

• threat_detection_external.go — Both buildInstallDetectionEngineForExternalDetectorStep and buildExternalDetectorExecutionStep replace their ~12-line setup blocks with a single call. The execution step layers its step-specific additions (NetworkPermissions, Mounts) on top:

// Before (repeated in both functions):threatDetectionData:=buildThreatDetectionWorkflowData(data, engineID)
threatDetectionData.Tools=map[string]any{"bash": []any{"*"}}
threatDetectionData.EngineConfig=&EngineConfig{ID: engineID}
ifcanReuseThreatDetectionEngineConfigForExternalDetector(data, engineID) {
threatDetectionData.EngineConfig=cloneThreatDetectionEngineConfig(...)
}
threatDetectionData.EngineConfig.Env=mergeThreatDetectionEngineEnv(...)
ifthreatDetectionData.EngineConfig.APITarget==""&&data.EngineConfig!=nil {
threatDetectionData.EngineConfig.APITarget=data.EngineConfig.APITarget
}
// After:threatDetectionData:=buildExternalDetectorWorkflowData(data, engineID)
// execution step only:threatDetectionData.NetworkPermissions=&NetworkPermissions{...}
threatDetectionData.SandboxConfig.Agent.Mounts=appendThreatDetectionRWMount(...)

@copilot merge main and recompile

Done in 27dd663. I merged origin/main into this branch and recompiled workflows, which updated the out-of-sync lock files.
