Report missing Fast Deployment packages as XA0132

[Copilot]

A successful-looking pm install can leave the package absent, including on CI emulators under storage pressure. After the existing reinstall attempt, Fast Deployment previously fell through to run-as, misreporting this condition as XA0137.

• Missing-package handling
  • Stop deployment when pm path still finds no package after forced reinstall.
  • Report XA0132 (PackageNotInstalled) instead of invoking run-as.

if (!await IsPackageInstalled (PackageName)) {
	LogDiagnosticDataError ("XA0132", Resources.XA0132_PackageNotInstalled);
	PrintDiagnostics ();
	LogCodedError ("XA0132", Resources.XA0132_PackageNotInstalled);
	return;
}

• Diagnostics

  • Preserve the existing pm path and /data free-space diagnostics for CI/infra investigation.

• Coverage

  • Add focused tests for pm path output classification.

Pull request overview

Updates Fast Deployment’s post-pm install verification so that if pm path <pkg> still fails to report the package after a forced reinstall, deployment stops and reports XA0132 (PackageNotInstalled) instead of continuing into the run-as probe (which previously could misreport this condition as XA0137). Adds unit tests covering the pm path output classification helper.

Changes:

• Stop FastDeploy deployment and emit XA0132 when pm path still shows no package after a reinstall attempt.
• Refactor pm path output detection into FastDeploy.IsPackageInstalledOutput.
• Add unit tests validating pm path output classification.
