[secops-soar] setup.py is missing python-dotenv dependency from install_requires

[dandye]

Description

server/secops-soar/setup.py is out of sync with server/secops-soar/pyproject.toml and is missing the python-dotenv dependency.

Root Cause

PR #259 added "python-dotenv>=1.0.0" to server/secops-soar/pyproject.toml to support import dotenv in secops_soar_mcp.bindings.

However, server/secops-soar/setup.py (lines 24-27) was not synchronized:

setup(
    name="secops-soar-mcp",
    version="0.1.2",
    packages=setuptools.find_packages(),
    install_requires=[
        "aiohttp>=3.11.15",
        "mcp[cli]>=1.4.1,<2.0",
    ],  # Missing python-dotenv>=1.0.0
    ...
)

Legacy packaging workflows, source distribution builds, or environments installing via setup.py will not pull in python-dotenv, leading to runtime ModuleNotFoundError: No module named 'dotenv' upon startup.

Proposed Fix

Synchronize server/secops-soar/setup.py by adding "python-dotenv>=1.0.0" to install_requires:

    install_requires=[
        "aiohttp>=3.11.15",
        "mcp[cli]>=1.4.1,<2.0",
        "python-dotenv>=1.0.0",
    ],
