feat(backend/chat): update CoPilot execution context mapping

Update run_block.py with proper CoPilot-to-graph context mapping:
- graph_id = copilot-session-{session_id} (agent = session)
- graph_exec_id = copilot-session-{session_id} (run = session)
- graph_version = 1 (versions are 1-indexed)
- Pass workspace_id and session_id for file operations
- Each chat session is its own agent with one continuous run
