Subject: [PATCH] fix: conditional requirements install and cross-platform venv
 activation

Closes #143

Dockerfile: COPY /requirements.txt failed at build time for
examples without a requirements.txt (web3, mcp-agents,
gemini-quickstart). Copy the example first, then pip install only when
requirements.txt exists.

setup.sh: hardcoded .venv/bin/activate breaks on Windows Git Bash/MSYS2,
where venv creates .venv/Scripts/activate. Source the correct script by
checking both paths, and fail with a clear message if neither exists.
