Story 3.2: Global Session Access

**As a** package developer,  
**I want** to access the session from anywhere in my code,  
**So that** I don't need to pass the session object through every function.

### Acceptance Criteria:
- **Given** a session has been initialized
- **When** I call a function to get the current session
- **Then** I receive the active session object without explicit parameter passing
