The feature directory contains network planning and design functionalities
(e.g., topology_planner), not device-specific features. These were not being
loaded because load_device_skills() only scanned the device directory.
Changes:
- Added new load_feature_skills() method in SkillsLoader
- Modified reload_skills() to load both device and feature directories
- Device skills: device-specific configurations (e.g., VPCS)
- Feature skills: network planning functionalities (e.g., topology planner)
- Both are now properly loaded into SKILLS_REGISTRY
This ensures that network planning features like topology_planner are available
via the device_skills tool with proper category classification.
- Add PacketAnalysisTool that accepts user-provided tshark arguments
- LLM constructs tshark commands based on protocol knowledge from skills
- Add PACKET_ANALYSIS_REGISTRY for protocol definitions
- Add load_packet_analysis_protocols() to SkillsLoader
- Add get_packet_analysis_protocol() and list functions to registry
- Register PacketAnalysisTool in teaching and lab automation modes
- Update SkillsManager to reload packet analysis protocols

## Summary
Add a complete fault injection system for GNS3 Copilot, migrate all
skills from local Python files to an external Git repository with
hot reload support, and restructure Copilot API under /copilot/.
## Key Changes
### Fault Injection
- New troubleshooting_injection mode with InjectionSkillsTool
- 368 fault scenarios across 39 protocol categories
- Context-based filtering (LLM must pass topology protocols)
### External Skills Repository
- SkillsManager: Git clone/pull, version tracking, smart updates
- SkillsLoader: YAML skills + Markdown prompts from external repo
- Hot reload via POST /copilot/reload/skills
- Configurable via gns3_server.conf
### Architecture
- API unified under /copilot/ prefix
- SkillsManager moved from Controller to agent module
- Lazy initialization with startup background preload
- Per-command Git timeout, smart update checks
- Forbidden commands hot-reloadable from external repo
- 32 INFO logs downgraded to DEBUG
