Disable threat detection on daily malicious code scan workflow

[Copilot]

The daily malicious code scan workflow was running an unnecessary threat detection step that analyzed the agent's output before creating code scanning alerts.

Changes

• Added threat-detection: false to safe-outputs section in .github/workflows/daily-malicious-code-scan.md
• Recompiled workflow to remove detection job and its dependencies from the lock file

Result

The workflow now runs without the detection step while still creating code scanning alerts for malicious code findings. The detection job (253 lines) and all related dependencies have been removed from the compiled workflow.

Before:

safe-outputs:
  create-code-scanning-alert:
    driver: "Malicious Code Scanner"

After:

safe-outputs:
  create-code-scanning-alert:
    driver: "Malicious Code Scanner"
  threat-detection: false

Technical Note

Threat detection is enabled by default for workflows with safe-outputs. Setting threat-detection: false explicitly disables the detection job that validates agent output before executing safe output operations.

Pull request overview

This PR aims to disable threat detection on the daily malicious code scan workflow to remove an unnecessary analysis step before creating code scanning alerts. However, the implementation has issues that need to be addressed.

Key Changes

1. Added threat-detection configuration to disable the detection step in the daily malicious code scan workflow (though incorrectly placed)
2. Recompiled workflow to remove the 253-line detection job and its dependencies
3. Unrelated changes to multiple test workflow files that appear to be from a different fix

The threat-detection: false configuration is incorrectly placed. According to the schema and code implementation, threat-detection should be at the same level as safe-output types (like create-code-scanning-alert), not nested under them.

Current (incorrect):

safe-outputs:
  create-code-scanning-alert:
    driver: "Malicious Code Scanner"
  threat-detection: false

Expected:

safe-outputs:
  create-code-scanning-alert:
    driver: "Malicious Code Scanner"
threat-detection: false

The threat-detection field should be a top-level frontmatter field, not nested within safe-outputs.

Suggested change

	threat-detection: false
	threat-detection: false

This PR contains unrelated changes to this test workflow file, including:

1. Reordering of language service installation steps (Go moved before TypeScript)
2. Adding GH_TOKEN environment variables to the Checkout PR branch step
3. Removing explicit environment variable passing from the gh pr checkout command

These changes are unrelated to disabling threat detection in the daily malicious code scan workflow and should be in a separate PR.

Suggested change

	await exec.exec("gh", ["pr", "checkout", prNumber.toString()]);
	await exec.exec("gh", ["pr", "checkout", prNumber.toString()], { env: { GH_TOKEN: process.env.GH_TOKEN } });
