Fix TestSetupCLIAction integration test string expectations

[Copilot]

TestSetupCLIAction was failing because test assertions expected strings that don't exist in install.sh.

Changes

• can_fetch_latest_without_input_version: Check for "using 'latest'" instead of "fetching latest" (matches actual script output: "No version specified, using 'latest'...")
• has_release_validation: Check for "Verifying binary" instead of "Validating release" (script has binary verification, not "release validation")

// Before
!strings.Contains(string(content), "fetching latest")
!strings.Contains(string(content), "Validating release")

// After  
!strings.Contains(string(content), "using 'latest'")
!strings.Contains(string(content), "Verifying binary")

This section details on the original issue you should resolve

<issue_title>CI: TestSetupCLIAction failing - missing expected strings in install.sh</issue_title>
<issue_description>## Summary

The TestSetupCLIAction integration test is failing on main branch and all PRs. The test expects certain strings in actions/setup-cli/install.sh that don't exist.

Failing Tests

• TestSetupCLIAction/can_fetch_latest_without_input_version
• TestSetupCLIAction/has_release_validation

Root Cause

The test in pkg/cli/setup_cli_action_integration_test.go checks for specific strings:

1. Line 54: Expects both "No version specified" AND "fetching latest" in the script

   • Script has: "No version specified, using 'latest'..."
   • Script missing: "fetching latest"

2. Line 87: Expects "Validating release" in the script

   • Script does not contain this string

Evidence

setup_cli_action_integration_test.go:55: Script should support fetching latest release when no version is provided
setup_cli_action_integration_test.go:88: Script does not include release validation

Fix Options

1. Update the test to match the actual strings in the script
2. Update the script to include the expected strings

Affected CI Runs

• Main branch: https://github.com/github/gh-aw/actions/runs/21681463772
• Multiple recent runs show this same failure

Pull request overview

This PR updates the TestSetupCLIAction integration test expectations so they match the actual output and behavior of actions/setup-cli/install.sh, fixing recurring CI failures. The test now looks for the real status messages emitted by the script for “latest” fallback and binary verification.

Changes:

• Updated can_fetch_latest_without_input_version to assert on "using 'latest'" instead of the non-existent "fetching latest" string, while still requiring "No version specified".
• Updated has_release_validation to assert on "Verifying binary" instead of "Validating release", aligning the test with the script’s binary verification step.
• Added a clarifying comment above the binary verification assertion to explain what behavior is being validated.
