Fix: Create PROFILE_DIR at module import time

This fixes the database initialization error on Hugging Face Spaces
by ensuring the ~/.agentic-content-generation directory is created
when src/profile.py is imported, before any database operations.

Changes:
- Added PROFILE_DIR.mkdir() at module level in src/profile.py
- Simplified main.py (directory now created at import)
- Fixes error: "Failed to create database engine"

The directory is now guaranteed to exist before DatabaseSessionService
tries to create the SQLite database.
