Two silent failures in the Python SDK prevented frontend context from reaching the agent:
1. langgraph_default_merge_state rebuilt copilotkit as {actions} only, dropping the
useCopilotReadable items the TypeScript runtime had placed in state.copilotkit.context.
2. CopilotKitContext.properties were never forwarded through execute_agent → agent.execute(),
so <CopilotKit properties={...} /> values never reached state.copilotkit.properties.
Both fields now land cleanly under state["copilotkit"] on every agent invocation.
Also adds tests, a showcase example, and a new docs page.
