* fix: handle PackageNotFoundError when commit-check is not installed

Wrap __version__ in try/except so that importing commit-check
does not crash in development environments where the package
has not been pip installed (e.g. running directly via uv or
python -m). Falls back to '0.0.0.dev'.

* test: add tests for __version__ fallback on PackageNotFoundError

_find_check in commit_check/util.py was no longer used by any
production code. Only its tests in tests/util_test.py referenced it.
Remove both the function and its corresponding test class.

fix: use pull_request_target for auto-labeler on fork PRs

When a PR is opened from a fork repository, the GITHUB_TOKEN in
pull_request events only has read permissions, preventing the
autolabeler from adding labels. Using pull_request_target runs
the workflow in the context of the base repository with write
permissions, which is safe since the autolabeler only reads PR
metadata and adds labels without checking out any code.

Fixes auto-labeler failing on PR #487 from a fork.

* fix: remove dead else branch in print_suggestion() (#486)

Removed the unreachable else branch in print_suggestion() that could never
be entered since all callers already guard with a truthy check. Updated the
type hint from str | None to str, and removed the corresponding test.

Close #486

* fix: resolve mypy type error in print_suggestion call

Fix the mypy error: the argument passed to print_suggestion in
_print_failure is now guaranteed to be str (still works at runtime,
just shuts up the type checker).
