fix(claude): use write_file_and_record and CONSTITUTION_REL_PATH in tests

Addresses two review comments:

- ensure_context_file now uses the base class's write_file_and_record()
  helper instead of Path.write_text + a separate record_file_in_manifest
  call. This matches the pattern used everywhere else in integrations,
  normalizes \r\n -> \n to avoid platform newline translation, and keeps
  the write+manifest update consistent.
- Tests now import and use CONSTITUTION_REL_PATH instead of hardcoding
  ".specify/memory/constitution.md", so the path stays in sync with the
  production constant.
