Valen 95fada4490 fix(sdk-python): fix emit_messages and emit_tool_calls config not working 
Fixes #2066

## Problem

`copilotkit_customize_config(config, emit_messages=False)` does not work -
TEXT_MESSAGE_* events are still emitted despite the configuration.

## Root Causes

1. **Metadata Reading Bug**: In `langgraph_agui_agent.py`, the code uses
   `getattr(raw_event, 'metadata', {})` to read metadata, but `raw_event`
   is a dict, not an object. This should use `.get()` instead.

2. **Encoder Crash Bug**: When the filtering logic works (after fixing bug #1),
   it returns `""` (empty string) to skip dispatching events. However, this
   empty string gets yielded to the event encoder which expects event objects
   with `model_dump_json()` method, causing an `AttributeError`.

## Fixes

1. Changed metadata reading to handle both dict and object cases.
2. Changed return value from `""` to `None` for filtered events.
3. Added `run()` method override to filter out `None` values before yielding
   to encoder.

Charlie Tonneslan fb613ad07a fix(sdk-python): add dict_repr method to LangGraphAGUIAgent 
Adds missing dict_repr() method to LangGraphAGUIAgent class to fix
AttributeError when SDK tries to serialize agent info.

The method was present in the parent LangGraphAgent class but not
overridden in LangGraphAGUIAgent, causing failures when calling
sdk.info() with AGUI agents in FastAPI integrations.

Fixes #2667
