fix(compile): use 'template' label for job/stage targets and fix header paths

- CLI now prints 'Generated job template:' and 'Generated stage template:'
  instead of 'Generated job pipeline:' / 'Generated stage pipeline:' since
  these targets produce reusable ADO templates, not standalone pipelines.
- Header comments in generated job/stage templates now reference the actual
  output path instead of deriving a path from the input file, fixing
  incorrect inclusion examples (e.g. showing ./agents/x.lock.yml when the
  output was at ./x.lock.yml).
