requirements.horizon.txt: dependency file for hosted mcp builds
selecting pyproject.toml in horizon installs the project bare (uv pip
install ./ — no extras), so fastmcp stays at the builder's 2.x pin and
the code-mode import fails at fastmcp inspect time. this file installs
.[mcp], pulling fastmcp>=3.4.2 + monty into the image
