feat: add psagentai agent with deployment and configuration
Initial project setup including the main agent script, configuration files, profile JSON state, systemd service unit, startup script, deployment documentation, and Python dependencies. Includes .env, venv/, and __pycache__/ which should likely be excluded via .gitignore to avoid committing secrets and artifacts.

Provides the 'spawn()' function, a front-end to various platform-

specific functions for launching another program in a sub-process.

Also provides the 'find_executable()' to search the path for a given

executable name.
