Brings tutorial/agent-graphs in line with the modernization that landed on main via #24 (devrel-agents-tutorial), plus the missing config_manager methods added on main in the offline-evals work that this branch never picked up. SDK migration: - pyproject.toml: launchdarkly-server-sdk-ai >=0.10.0 -> >=0.20.0; drop [tool.uv.sources] git override pinning to python-server-sdk-ai@main - config_manager.py: from ldai.client -> from ldai - Replace removed `config.tracker` attribute with `config.create_tracker()` across config_manager.py, generic_agent.py, ld_agent_helpers.py, agent_service.py, api/main.py - In generic_agent.py hoist `tracker = agent_config.create_tracker()` once so the try/except shares a single tracker Fix pre-existing import-time AttributeError on this branch: - agent_service.AgentService.__init__ calls `self.config_manager.clear_cache()` and `self.config_manager.get_agent_graph(...)` but neither existed on FixedConfigManager in this branch. Port both from main (clear_cache is a no-op; get_agent_graph wraps ai_client.agent_graph). Verified by importing config_manager, agents.ld_agent_helpers, agents.generic_agent, api.services.agent_service, and api.main in a fresh venv with launchdarkly-server-sdk-ai 1.0.1.

This branch was broken at import time before this PR:
AgentService.__init__callsself.config_manager.clear_cache()andagent_service.py:50callsself.config_manager.get_agent_graph(...), but neither was defined on this branch'sFixedConfigManager. Both methods were added onmain(commitdbdf4e9, "Add offline-evals tutorial companion") and never picked up here. Ported with no logic changes.Test plan
