Add comprehensive packet filter management functionality to GNS3-Copilot, enabling AI-powered fault injection scenarios with network simulation capabilities like latency, packet loss, and corruption. ## Changes ### New Features - **GNS3PacketFilterTool**: New LangChain tool for managing packet filters on GNS3 links with support for delay, packet loss, corruption, frequency_drop, and BPF filtering - Actions: get_available, set, get, clear - Integrated into troubleshooting_injection mode for fault scenarios ### API Integration - **Link.available_filters()**: Added method to custom_gns3fy.py Link class - Queries available filter types for specific links - API v3+ only (raises ValueError for v2 connectors) - Returns filter definitions with parameters and constraints ### Tool Integration - Added GNS3PacketFilterTool to TROUBLESHOOTING_INJECTION_MODE_TOOLS - Positioned as 3rd tool in fault injection workflow - Optimized for troubleshooting practice scenarios ## Files Modified - gns3server/agent/gns3_copilot/agent/gns3_copilot.py - gns3server/agent/gns3_copilot/gns3_client/custom_gns3fy.py - gns3server/agent/gns3_copilot/tools_v2/__init__.py ## Files Added - gns3server/agent/gns3_copilot/tools_v2/gns3_packet_filter.py ## Testing - All validation tests passed - Version checking verified (v3+ only) - Tool integration confirmed in troubleshooting mode
