ONE external plugin memory provider.

Single integration point in run_agent.py. Replaces scattered per-backend
code with one manager that delegates to registered providers.

The BuiltinMemoryProvider is always registered first and cannot be removed.
Only ONE external (non-builtin) provider is allowed at a time — attempting
to register a second external provider is rejected with a warning.  This
prevents tool schema bloat and conflicting memory backends.

Usage in run_agent.py:
    self._memory_manager = MemoryManager()
    self._memory_manager.add_provider(BuiltinMemoryProvider(...))
    # Only ONE of these:
    self._memory_manager.add_provider(plugin_provider)

    # System prompt
    prompt_parts.append(self._memory_manager.build_system_prompt())

    # Pre-turn
    context = self._memory_manager.prefetch_all(user_message)

    # Post-turn
    self._memory_manager.sync_all(user_msg, assistant_response)
    self._memory_manager.queue_prefetch_all(user_msg)
