* refactor: Extract build and disconnect handling into separate modules
This commit separates the build and disconnect handling logic from the chat API module into dedicated files:
- Created `langflow/api/build.py` to house the flow generation and vertex building logic
- Created `langflow/api/disconnect.py` to manage the custom streaming response with disconnect handling
- Removed duplicate code from `langflow/api/v1/chat.py`
- Improved code organization and modularity
* refactor: Extract flow build and event handling methods in build API
This commit introduces two new methods in the build API to improve code organization and reusability:

* Fixed source and targets Y to work on loop edges as well
* feat: Add session ID support to tracing service
This commit adds support for setting the session ID in the tracing service. Two methods have been modified:
- In the `Graph` class, the `set_session_id` method has been added to set the ID of the current session.
- In the `ArizePhoenixTracer` class, the `__init__` method has been modified to accept a `session_id` parameter and store it.
These changes enable the tracing service to associate traces with specific sessions, improving trace management and analysis.
* refactor: Improve tracing session ID handling in Graph class
- Rename `set_session_id()` method to `set_tracing_session_id()`
- Add null check for tracing service when setting session ID
- Enhance method to only set session ID when tracing service is available
