fix(executor): pass config to _extract_state for langgraph-prebuilt >= 1.1.0

[samarth70]

Fixes #213.

Problem

langgraph-prebuilt 1.1.0 changed ToolNode._extract_state to require a config parameter:

def _extract_state(
    self,
    input: list[AnyMessage] | dict[str, Any] | BaseModel,
    config: RunnableConfig,
) -> ...

ExecutorToolNode._build_tool_runtime still calls self._extract_state(input), so once the floating langgraph>=1.0.2,<2.0.0 pin resolves to 1.1.x, every tool execution raises:

TypeError: ToolNode._extract_state() missing 1 required positional argument: 'config'

Fix

Forward the config that is already a parameter of _build_tool_runtime:

state = self._extract_state(input, config)

Tests

Added tests/mobile_use/test_executor_tool_node.py — an offline regression test that drives _build_tool_runtime directly:

• fails on the old call with the exact reported TypeError (verified against langgraph-prebuilt 1.1.0)
• passes with the fix, asserting the resulting ToolRuntime carries the extracted state, the config, and the tool call id

Verified locally: pytest tests/mobile_use/test_executor_tool_node.py → 1 passed; ruff format --check and ruff check clean on both files.
