Description

Part of #1103, ruling 2: the util scripts' syntax floor rises from 3.7 to 3.8, matching requires-python.

• Tests:
  • TestStandardLibraryOnly in test_actions_helper_2047 and the five test_release_*_1967 syntax checks now parse at FLOOR. FLOOR is imported from test_requires_python_floor_2051, the test that pins requires-python, so the version isn't a new literal.
  • Names say 3.8.
  • The self-documenting f-string check is removed: f'{x=}' is valid 3.8 syntax, and it existed only because 3.7 parsing accepted it.
• Prose: the util/_actions.py and seven util/release_*.py docstrings say 3.8, as does workflows.rst's _actions.py sentence. With docstrings stripped, every util file's AST matches main.
• Proof: a walrus expression is rejected at feature_version=(3, 7) and accepted at (3, 8). The change loosens a check, so there is no failing-without-it test.
• Tests run: the floor tests and the tier guard (222), the reset-build test (7), and the 22 tests/project files that read workflows.rst (452) all pass.
• Overlap: docs(repo): fifth whole-repo pass over the repository files (#1103) #2158 rewrites the same util/_actions.py paragraph. Whichever lands second takes docs(repo): fifth whole-repo pass over the repository files (#1103) #2158's wording with "3.8's syntax".

Rebased onto main after #2158 merged: 05db861a4 → 9c6b5e322.

• Conflict: one paragraph in util/_actions.py's docstring, which docs(repo): fifth whole-repo pass over the repository files (#1103) #2158 reworded. I kept docs(repo): fifth whole-repo pass over the repository files (#1103) #2158's wording and changed only "3.7's syntax" to "3.8's syntax". That line is now this PR's sole difference in the file.
• Everything else is unchanged; git range-diff shows that hunk only.
• Checks: with docstrings stripped, every util file's AST matches main. The floor tests and the tier guard pass (229).

CI runs again on the new head. The cross-review in flight also covers this delta.

Review: GOOD TO GO at 9c6b5e322 (Sonnet): all 34 util files match main's AST once docstrings are stripped. FLOOR is (3, 8) and is pinned by the requires-python test. Importing it adds no test collections. Removing the f-string check is justified, no util syntax-floor claim for 3.7 remains, and the tests pass (229).
