📝 Walkthrough

Walkthrough

This change relocates tool definitions from the realtime module to a dedicated tools module. WebSearch, XSearch, and FileSearch are moved to a new tools.py file and re-exposed at the top level of the xai plugin package, while removing them from realtime module exports.

Changes

Cohort / File(s)	Summary
Tool Definition Consolidation livekit/plugins/xai/tools.py, livekit/plugins/xai/realtime/realtime_model.py	New module tools.py introduces abstract base class XAITool and three concrete dataclasses (WebSearch, XSearch, FileSearch) with to_dict serialization methods. Corresponding definitions removed from realtime_model.py; imports updated to remove abstractmethod, dataclass, field.
Public API Reorganization livekit/plugins/xai/__init__.py, livekit/plugins/xai/realtime/__init__.py	Top-level __init__.py now imports and exports WebSearch, XSearch, FileSearch from .tools. Realtime module's __init__.py no longer exports these tools; imports restricted to RealtimeModel only.
