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.

# a simple Qt image interface.

# history:
|
|
# 2006-06-03 fl: created
|
|
# 2006-06-04 fl: inherit from QImage instead of wrapping it
|
|
# 2006-06-05 fl: removed toimage helper; move string support to ImageQt
|
|
# 2013-11-13 fl: add support for Qt5 (aurelien.ballier@cyclonit.com)
