Proof of Concept: Adding lifecycle events.
Added AGUI events to vertices and the graph. Created Decorator to add observability to Langflow workflows. TODO: Unit tests, feature gating to nullify impact in current production code paths.
Added unit tests for lifecycle_events. Refraining from using event_manager for now since this capability is goig to stay dormant until APIs are ready for streaming.
Added unit tests for before_callback_event and after_callback_event in graph and vertex classes.

* perf(lfx): lazy import CLI commands to reduce cold start time
Defer imports of serve_command and run until the specific subcommand
is invoked. Previously, both commands were imported at module load,
causing `lfx run` to unnecessarily load serve-specific dependencies
like uvicorn, rich.console, and rich.panel.
This optimization is particularly important for Knative/serverless
deployments where cold start latency matters due to scale-to-zero.
* refactor: eliminate temporary file usage for JSON input processing
* feat: add .claude to .gitignore
* refactor: implement lazy import for serve_command in LFX CLI module
* refactor: optimize imports in run.py for improved performance
* refactor: update type hints for Graph in script_loader and validation modules
* refactor: move imports for BaseChatPromptTemplate and PromptTemplate to TYPE_CHECKING block
* refactor: streamline lazy imports and enhance __getattr__ for field typing constants
* refactor: update patch target for get_settings_service in validation tests
* refactor(lfx): simplify field_typing lazy import per PR review
Replace explicit _exports dictionary creation with direct getattr(constants, name)
to avoid redundantly importing all constants on each attribute access.
This addresses the Copilot review comment on PR #10739.
* test(lfx): add comprehensive tests for lazy import mechanisms
Add tests to verify lazy import patterns work correctly:
- field_typing/__init__.py: Test all exports via __getattr__ including
Input, Output, RangeSpec, Data, and all langchain type constants
- cli/__init__.py: Test serve_command lazy loading via __getattr__
- __main__.py: Test wrapper commands exist and are callable
- run.py and script_loader.py: Test module imports and functions
- validation.py: Test functions work correctly after lazy import changes
- flow_dict handling: Test JSON parsing for in-memory flow processing
These tests address CodeRabbit's pre-merge check concerns about missing
test coverage for the lazy import optimizations.
