  """Reads, validates, and returns the pipeline configuration.

  All validation happens here so that every stage fails at the same gate,
  before any dataset walk or GPU work. On success the returned object is
  fully typed and internally consistent.

  Args:
      config_path: Path to the YAML configuration file.

  Returns:
      A validated :class:`PipelineConfig`.

  Raises:
      ConfigError: If the file is missing, is not valid YAML, is missing
          required fields, contains out-of-range values, or names a
          ``prompt_to_detect`` that has no block under ``prompts``.
