Description of your pull request and other information

Closes #2061. Since #2053, setup.py held nothing but a Python 2 guard and a bare setup(); everything else is declared in pyproject.toml.

• Removed: setup.py and tests/project/test_setup.py. examples/benchmark/Dockerfile no longer copies setup.py.
• Build unchanged: the 3.14 wheel's unpacked files match main's exactly under diff -r. The sdist loses only the two deleted files. pip install -e . works (PEP 660), and pip wheel on 3.8 succeeds.
• Dependabot: the reason for the static readme changes. Dependabot's file fetcher (fetch_project_file) now builds the Pipfile's editable from pyproject.toml alone, instead of from its stub setup.py. The comment and test_actions_pinned_1968 are reworded to match.
• Guard test: test_no_setup_py_2061 fails if setup.py comes back, or if a Dockerfile COPY names an untracked path. A self-check stops the parser passing vacuously by finding nothing. I confirmed it fails before the fix in both of those ways.
• Tests: the project leg ran 1946 tests with 0 failures. The packaging, changelog and docs readers give 265 passed.

GOOD TO GO at 15db89cee (Sonnet cross-review). The wheels from main and from this branch unpack identically under diff -r. The sdist loses only the removed files. pip install -e works and imports from the tree. No workflow, Makefile, MANIFEST.in, conda recipe or README step runs or copies setup.py. The guard test fails with setup.py restored and with it re-added to the Dockerfile COPY, and the readers give 368 passed.

Two non-blocking fixes are coming in one amend:

• Stale comment: the one in unit-tests.yml still uses setup.py as its example code file.
• Dependabot wording: dependabot-core's source does fetch pyproject.toml when setup.py is missing and passes it through unstubbed. It does not show that a dynamic readme would fail, so the wording will claim only what the source shows.

[JarryShaw]

Pushed e80e32ca1, which changes wording only.

• Dependabot: the pyproject.toml comment, the test_actions_pinned_1968 docstrings, the changelog entry and the commit message now claim only what dependabot-core's source shows. With no setup.py, fetch_project_file fetches pyproject.toml in its place, and the Pipfile updater writes it unstubbed. The static readme stays, because it doesn't depend on what a stub would supply.
• unit-tests.yml: nothing to change. No comment there names setup.py; the only hits are setup-python.
• Checks: changelog --check is in step, and the six readers give 166 passed. The GOOD TO GO carries to e80e32ca1.

Per-file detail: the coverage-html artifact of this run.

[JarryShaw]

Ready to merge at e80e32ca1: the review is GOOD TO GO and CI is complete (56 passed, 0 failed). The ordering leg ran 1946 tests with 0 failures. The 3.8–3.10 KTLO legs show 0 failing tests, and the PR is based on current main (c98541f84). #2064 edits the same pyproject.toml and changelog, so whichever merges second will get a conflict, and I'll rebase it.

[JarryShaw]

Still ready after #2064 merged. The branch is only BEHIND: it merges cleanly into main (d7581ebb1), so I haven't pushed a rebase. On the merged tree, CHANGELOG.md is still in step, and the setup.py guard, the setuptools-floor test, the Dependabot-pin test and the changelog and docs readers all pass.
