fix(_types): ParsedName repr names the token behind each ambiguity

[derek73]

Summary

• ParsedName.__repr__ rendered the ambiguities line as [a.kind.value for a in self.ambiguities], so two distinct Ambiguity objects of the same kind about different words collapsed into identical-looking entries (['suffix-or-name', 'suffix-or-name']), reading as a double-emit bug in the emitter rather than the two separate, correctly-distinct calls they are.
• Follows Ambiguity.__repr__'s own token-join convention ("/".join(t.text for t in self.tokens)) so each entry names its token(s): ['suffix-or-name: MA', 'suffix-or-name: V']. Falls back to bare kind.value when an ambiguity has no tokens (e.g. UNBALANCED_DELIMITER).

Fixes #431

Test plan

• Updated tests/v2/test_reprs.py::test_parsedname_repr_includes_ambiguities_line_when_present for the new format
• Added tests/v2/test_reprs.py::test_parsedname_repr_distinguishes_same_kind_ambiguities_by_token, a regression test for the exact two-ambiguity case from the issue
• Full suite passes: uv run pytest -q → 5924 passed, 154 skipped, 9 xfailed
