check-deps shows "pyyaml missing" even when installed and importable

[ak1t4]

Description:
The command mcp-task-orchestrator-cli check-deps reports pyyaml as "missing" even though it is correctly installed in the environment (via pipx, venv, or pip) and can be imported manually with import yaml.

Steps to reproduce:

1. Create and activate a venv (or use pipx).
2. Install dependencies with pip install -r requirements.txt or pip install pyyaml.
3. Run mcp-task-orchestrator-cli check-deps or setup.

Expected result:
The dependency checker should correctly detect pyyaml and allow continuing.

Actual result:
It always shows pyyaml as missing, blocking the use of the setup flow.

Verification:

venv/bin/python -c "import yaml; print(yaml.__version__)"
# Output: 6.0.2

Environment:

• OS: macOS (Homebrew)
• Python: 3.13.x
• Both pipx and venv tested, same issue.

Note:
Other macOS/Homebrew users are experiencing the same problem.

Identical problem, it just refuses to run:

I've decided to move to a larger ecosystem, as seen explained here. You can find this larger project at: https://github.com/EchoingVesper/vespera-atelier. The task orchestrator component (now renamed "Vespera Scriptorium") is intended to be continued to be usable (and hopefully with a functional installer in the new install.py) as both an MCP server and also as a component or library in my larger creative suite project. There is still much work to be done on it, but it will proceed over there. Consider this repository deprecated (although it will remain for reference if problems arise in the new location).
