Python projects could only be started as `python -m <startModule>`, so
FastAPI/ASGI apps that run under uvicorn (like evo-ai:
`uvicorn app.main:app`) couldn't be started by zstart in either port.
Add an optional `startApp` field. When set, zstart runs
`uvicorn <startApp> --host <bind-host> --port <ports.dev> --reload` via
the venv python's -m (no PATH juggling), integrating zstart's existing
bind-host and dev-port handling. startApp takes precedence over
startModule; a python project still needs one or the other. Applied to
bash and PowerShell, documented in the README + example configs.
Config-driven PowerShell scripts to run infrastructure tasks (deploy, restart, backup, diagnostics) yourself instead of having an AI agent orchestrate them, to save agent tokens. Environment specifics live in zconfig.json (gitignored).
