Library packaging: import as babel_validation + split runtime/dev deps

[gaurav]

Stacked on #67 (base branch is add-github-issue-tests, not main). This is the first of two follow-up PRs that make the GitHub-issue test framework usable as an installable library; see #67 for how they relate.

This PR is the packaging groundwork — no behavior change.

Changes

• Rename the import package src.babel_validation → babel_validation (40 references across 17 files; purely mechanical). Filesystem paths (src/babel_validation/... in comments/docs) are unchanged — the code still lives under src/.
• Ship src/babel_validation as the top-level wheel package (was the whole src/ dir), so consumers import babel_validation rather than the non-idiomatic src. prefix (which could also collide with a consumer's own top-level src/). Drops the now-dead src/__init__.py.
• Repoint the csv-to-babeltests console script at babel_validation.tools.*.
• Split dependencies: keep only runtime deps (requests, pyyaml, pygithub, python-dotenv, click, tqdm, filelock) in [project.dependencies] so library consumers don't pull the test stack. Move pytest/pytest-xdist/pytest-subtests/pytest-timeout/deepdiff/openapi-spec-validator/black into a uv [dependency-groups] dev group — uv run/uv sync install it for local dev + CI, but it is never shipped to consumers.

PyGitHub stays a core dependency: issue-test definitions live in GitHub issues, so every consumer needs it to fetch them.

Verification

• uv run pytest -m unit → green (49 passed).
• uv build produces a wheel whose only top-level entry is babel_validation (no src/); import babel_validation works; import src.babel_validation no longer resolves from an install.

Pull request overview

Packaging-focused change to make src/babel_validation install as the canonical import package babel_validation (dropping the src. import prefix), while separating runtime dependencies from development/testing dependencies.

Changes:

• Renames imports across tests and library code from src.babel_validation.* to babel_validation.*, and updates doc regeneration commands accordingly.
• Adjusts wheel packaging to ship only src/babel_validation as the top-level wheel package and repoints the csv-to-babeltests console script.
• Splits runtime vs dev dependencies using uv dependency groups and updates uv.lock to reflect the split.
