Automated PR from SWE Destroyer agent.

Prompt: /linear AGX1-98 Add a comment to the top of the setup.py file explaining what the project does

Greptile Summary

This PR adds descriptive comments explaining the project's purpose. A one-line comment is added at the top of pyproject.toml, and a new setup.py file is created with a detailed header comment and a bare setuptools.setup() call.

• pyproject.toml: Harmless one-line comment addition — no functional impact.
• setup.py (new file): Introduces a setuptools-based setup.py alongside the existing hatchling build backend defined in pyproject.toml. The file serves no build purpose since the project's metadata, dependencies, and package discovery are all configured through hatchling. Running it directly via python setup.py would produce a broken/empty package. Consider whether this file is necessary given modern PEP 517 tooling.

Confidence Score: 4/5

• This PR is safe to merge — it adds only comments and a no-op setup.py that won't affect normal builds.
• The pyproject.toml change is purely cosmetic. The new setup.py won't interfere with PEP 517 builds, but it introduces a potentially confusing secondary build entry point that could produce broken results if invoked directly. Low risk overall.
• setup.py — the new file introduces a setuptools shim alongside the hatchling build backend, which could confuse contributors.

Important Files Changed

Filename	Overview
pyproject.toml	Adds a one-line comment at the top describing the project. No functional change.
setup.py	New file: adds a setup.py with a descriptive comment header and a bare setup() call. The project already uses hatchling as its build backend via pyproject.toml, so this setup.py could cause confusion or build conflicts if invoked directly.
