refactor(release): rename ParsePath enum to TokenizationRoute

ParsePath collided with pathlib.Path in mental models, and was one
letter from the parse_path attribute that stores its value — confusion
on confusion. Road (EASY/SHITTY/PATH_OF_PAIN) is the parser-confidence
axis; TokenizationRoute (DIRECT/SANITIZED/AI) is the tokenization-method
axis. They're orthogonal and the new name makes that obvious.

Field name parse_path stays — it's the right name for the attribute
that *holds* the route. String values ("direct", "sanitized", "ai")
stay too, so YAML fixtures and the analyze_release tool spec are
unchanged. Only the type symbol changes:

- value_objects.py: class rename + docstring spelling out orthogonality
  with Road.
- services.py: 3 call sites.
- scoring.py: docstring cross-reference updated.
- tests/domain/release/test_parser_v2_scoring.py: import + 3 call sites.
