Fix hancock OSS-Fuzz integration: system deps, atheris install, copyright year

[Copilot]

Three blockers in the hancock OSS-Fuzz integration files that would prevent the PR from building or being merged.

projects/hancock/Dockerfile

• Fix copyright year: 2026 → 2025
• Add nmap and libmaxminddb-dev to apt-get install — required at runtime by python-nmap and maxminddb respectively; absent from the base image
• Clean apt cache with && rm -rf /var/lib/apt/lists/*

RUN apt-get update && apt-get install -y python3-dev nmap libmaxminddb-dev \
    && rm -rf /var/lib/apt/lists/*

projects/hancock/build.sh

• Fix copyright year: 2026 → 2025
• Add explicit pip3 install atheris before the requirements.txt install — all 8 fuzz targets import atheris but it is not in requirements.txt, so fuzz targets would fail to build without this

pip3 install atheris
pip3 install -r "$SRC/hancock/requirements.txt"

Required changes:

Required changes:

• Change Copyright 2026 to Copyright 2025
• Add pip3 install atheris before the requirements.txt install as a safety net (atheris is the fuzzing framework all 8 fuzz targets depend on)
