Fixes #4894.

TensorRT 11.3 removed tools/Polygraphy/setup.py and setup.cfg and switched the Makefile and install.ps1 to python -m build --wheel, as the CHANGELOG's v0.49.34 entry describes ("Migrated the build system to pyproject.toml"). The pyproject.toml itself wasn't included, so building Polygraphy from source fails:

ERROR Source .../tools/Polygraphy does not appear to be a Python project: no pyproject.toml or setup.py

This adds a pyproject.toml that reproduces the metadata of the polygraphy 0.53.6 wheel on PyPI: the version from polygraphy.__version__, the description, README.md as the long description, the license, author, classifiers and homepage, Requires-Python: >=3.8, and the polygraphy console script. Only the polygraphy package is included, as tests/test_packaging.py expects.

project.license keeps the table form, { text = "Apache 2.0" }, because that is what gives the published wheel its License: Apache 2.0. setuptools 83.0.0 warns that the table form is deprecated and has to be replaced by 2027-02-18. An SPDX expression would change the published metadata, so I've left that choice to you.

Testing (x86_64-linux, Python 3.14.8, setuptools 83.0.0, on v11.4, which is the same commit as main):

• The wheel has the same 192 package files as the PyPI 0.53.6 wheel, with the same contents, and the same entry_points.txt, top_level.txt and METADATA body. The differences:
  • METADATA adds License-File: LICENSE.txt and Dynamic: license-file, and the dist-info has licenses/LICENSE.txt;
  • WHEEL has Generator: setuptools (83.0.0), where PyPI's has (84.0.0);
  • there's no zip-safe file.
• These 10 test modules, which don't import TensorRT, pass (285 passed, 4 skipped): tests/backend/base/test_loader.py, tests/common/test_interface.py, tests/common/test_struct.py, tests/comparator/test_compare.py, tests/comparator/test_postprocess.py, tests/func/test_func.py, tests/logger/test_logger.py, tests/mod/test_exporter.py, tests/mod/test_util.py and tests/test_deprecated_aliases.py.
• Not tested: make install and install.ps1 themselves, tests/test_packaging.py (it needs pytest-virtualenv and network access), and the other test modules, including all of those that import TensorRT.

AI disclosure: this change and description were prepared with Claude Code (Claude Opus 5.5); the commit carries a Co-Authored-By: Claude trailer.
