Summary

• Fix Go template whitespace trimming in application.yaml.tmpl that caused sources: and destination: to render at column 0 instead of under spec:, producing invalid YAML
• Add TestGenerate_ApplicationYAMLStructure unit test that parses generated ArgoCD Application YAML and validates the document structure (spec.sources, spec.destination, spec.source.path)
• Add assertValidYAML checks to existing ArgoCD deployer tests
• Add yamllint validation to the e2e argocd-deployer step
• Exclude bundle/ from yamllint (generated output, already gitignored)

Close #410

Test plan

• make test passes
• make lint-go passes (0 issues)
• make e2e passes (17/17 including yamllint on ArgoCD bundle output)
• make qualify passes
