fix: Fixes parameterized global artifacts resolution in exit handlers. Fixes #11610

[ItielOlenick]

Fixes #11610

Motivation

Workflows with parameterized global artifact names (e.g., globalName: output-result-{{inputs.parameters.variable}}) fail validation in exit handlers after v3.4.6 with
errors like "failed to resolve {{workflow.outputs.artifacts.output-result-car}}". This worked correctly in v3.4.5 and earlier.

Modifications

• Added pre-scan in exit handler validation to detect parameterized global artifacts
• Enable anyWorkflowOutputArtifactMagicValue when parameterized global artifacts exist
• Added comprehensive unit tests covering the regression scenario

Verification

• Unit tests reproduce the exact failure and verify the fix
• Existing validation tests continue to pass
• Runtime artifact resolution remains unchanged

Documentation

No documentation changes needed - this restores existing functionality that was inadvertently broken.
