pipecat/changelog/4395.changed.md

• Broadened tool_resources to app_resources for easy access not just in tool handlers but in other places like custom FrameProcessors. Three changes: a rename (tool_resources → app_resources), a new app_resources property on PipelineTask, and a new pipeline_task property on FrameProcessor. Tool handlers now read params.app_resources; custom processors read self.pipeline_task.app_resources. The previous tool_resources aliases (on PipelineTask, FunctionCallParams, and FrameProcessorSetup) keep working but are deprecated as of 1.2.0 and emit DeprecationWarnings.
