feat/node-input-audio

[MD4]

Description

This pull request introduces support for audio input devices throughout the stack, enabling the UI and backend to list and use audio input devices as node inputs. It includes new models and repository functions for device discovery, API routes for device listing, and the integration of a new "audio input" node in the UI. Additionally, it updates how control and device IDs are handled for consistency.

Changes Made

Device Audio Input Support

• Added new Zod models for audio devices (deviceAudioInput, deviceAudioOutput, and deviceAudio) in lib-models, and exported them in the index. [1] [2] [3]
• Implemented device repository functions in lib-shared to list audio input and output devices using node-web-audio-api, and exported these from the repository index. [1] [2] [3]
• Created API service and route handlers in service-api to expose /device/audio/input and /device/audio/output endpoints, and integrated them into the main route configuration. [1] [2] [3]

UI Integration for Audio Input Nodes

• Added a new NodeInputAudio React component and registered it as a node type, updated the node library and node creation logic to support "input-audio" nodes, and implemented a repository hook for fetching available audio input devices. [1] [2] [3] [4] [5] [6] [7]

Program and Runner Domain Changes

• Updated the program compiler and runner state types to use string-based keys for controls and devices, ensuring correct mapping and extensibility for new input types. [1] [2] [3]

UI Node Improvements

• Fixed the node input time type to use the correct model, adjusted node style for max width, and made minor improvements to the input control node's handle placement. [1] [2] [3] [4]
