… stdin Running `canopy-mcp --help` from a shell used to fall through to `mcp.run(transport="stdio")`, which read EOF from a TTY stdin and crashed with a Pydantic JSON validation error — the first thing a fresh pipx-installer would see. Add explicit --help / -h handling that prints usage text and exits, mirroring the existing --version branch. Bump to 3.1.1, add changelog entry.

Summary
canopy-mcp --helpused to fall through tomcp.run(transport="stdio"), read EOF from the TTY, and crash with a Pydantic JSON validation error. That's the first thing a freshpipx install canopy-cliuser hits when they try to inspect the binary. Adds explicit--help/-hhandling that prints usage and exits, mirroring the existing--versionbranch.Why a patch release
The bad UX ships in v3.1.0 (just published to PyPI). Cutting v3.1.1 immediately so new pipx-installers don't trip on it.
