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.

+class WSGITransport(BaseTransport):
+    """
+    A custom transport that handles sending requests directly to an WSGI app.
+    The simplest way to use this functionality is to use the `app` argument.
+
+    ```
+    client = httpx.Client(app=app)
+    ```
+
+    Alternatively, you can setup the transport instance explicitly.
+    This allows you to include any additional configuration arguments specific
+    to the WSGITransport class:
+
+    ```
+    transport = httpx.WSGITransport(
+        app=app,
+        script_name="/submount",
+        remote_addr="1.2.3.4"
+    )
+    client = httpx.Client(transport=transport)
+    ```
+
+    Arguments:
+
+    * `app` - The WSGI application.
+    * `raise_app_exceptions` - Boolean indicating if exceptions in the application
+       should be raised. Default to `True`. Can be set to `False` for use cases
+       such as testing the content of a client 500 response.
+    * `script_name` - The root path on which the WSGI application should be mounted.
+    * `remote_addr` - A string indicating the client IP of incoming requests.
