Fix setuptools configuration and CLI entry point in pyproject.toml

[Copilot]

The package could not be installed due to missing setuptools package discovery configuration, and the CLI entry point referenced a non-existent module af_server_client instead of af_client.

Changes

• Added setuptools package discovery: Configured [tool.setuptools.packages.find] to locate af_client and its subpackages (core, _mock)
• Fixed CLI entry point: Changed af_server_client.cli:main → af_client.cli:main

 [project.scripts]
-af-tcp-client = "af_server_client.cli:main"
+af-tcp-client = "af_client.cli:main"

 [build-system]
 requires = ["setuptools>=68.0.0", "wheel"]
 build-backend = "setuptools.build_meta"

+[tool.setuptools.packages.find]
+where = ["."]
+include = ["af_client*"]

This enables successful installation via pip install -e . and proper registration of the af-tcp-client command.

Original prompt

Problem

The project cannot be installed correctly because pyproject.toml is missing critical setuptools configuration and has an incorrect CLI entry point path.

Current Issues

1. Missing setuptools package configuration: The pyproject.toml uses setuptools as the build backend but doesn't specify where the package code is located, causing Poetry to fail with:

   Error: The current project could not be installed: No file/folder found for package af-tcp-client
   

2. Incorrect CLI entry point: The [project.scripts] section references af_server_client.cli:main, but the actual module is named af_client.

Solution

Update pyproject.toml with the following changes:

1. Add [tool.setuptools] section with explicit package configuration:

   [tool.setuptools]
   packages = ["af_client"]

2. Fix the CLI entry point from af_server_client.cli:main to af_client.cli:main

Updated pyproject.toml

Testing

After these changes, users should be able to install the project successfully:

poetry install --no-cache

This will properly install both the af_client package and make the af-tcp-client CLI command available.
