- Register packet_analysis_skills as a LangChain tool for LLM
- LLM can query protocol field definitions before calling packet_analysis
- Follows the same pattern as DeviceSkillsTool and InjectionSkillsTool
- Delete packet_capture_tools.py (analyze_packets with packet_number)
- PacketAnalysisTool is more flexible and can do everything the old tool could
- Update tool registration to use only PacketAnalysisTool
- Cleaner, more unified packet analysis interface
- 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

Add missing dependencies for the external skills repository feature:
- PyYAML>=6.0.0: for loading YAML skill files
- GitPython>=3.1.0: for Git operations (clone/pull) on skills repo
These dependencies are required by the SkillsManager and SkillsLoader
classes introduced in commit e68cc17e.

## 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
DeepSeek models (deepseek-v4-flash/pro) enable thinking mode by default,
which returns reasoning_content that must be passed back to the API in
subsequent requests. This causes 400 errors in multi-turn conversations
when the reasoning_content is not properly handled.
This commit disables thinking mode by passing extra_body={"thinking": {"type": "disabled"}}
as an explicit parameter to DeepSeek models, preventing the reasoning_content
field from being generated.
Modified:
- create_base_model(): Add extra_body parameter with thinking mode disabled
- create_title_model(): Add extra_body parameter with thinking mode disabled

When importing a project, the round-robin logic would attempt to distribute
nodes across all configured compute resources, including offline ones. This
caused import failures when any remote compute was unreachable.
This fix filters the compute list to only include connected computes before
round-robin distribution. If no remote computes are connected, all nodes
are assigned to the local compute.
This matches the approach used in project._get_disconnected_computes() and
prevents the issue where importing a project fails with:
"Cannot connect to compute 'X' with request POST /projects"
Fixes issue introduced in commit 90e3a8d6 (2017) which added round-robin
load balancing without considering offline compute nodes.

Fix F821 undefined name 'status' error by importing the status
module from fastapi. This resolves build errors when using
status.HTTP_403_FORBIDDEN and status.HTTP_404_NOT_FOUND.
Add exception handling in stop_wrap_console to gracefully handle
ConnectionResetError, BrokenPipeError, and OSError when waiting
for console writer to close.
This prevents 500 errors when stopping QEMU nodes if the console
connection is reset before the writer finishes closing.
Fixes race condition where QEMU process exits and closes connections
before the console writer cleanup completes.
Remove MD5 checksum calculation from the node files API since
disk image files are dynamic and change frequently. MD5 calculation
was also causing significant performance overhead.
Changes:
- Remove md5sum field from NodeFile schema
- Remove MD5 calculation from list_node_files method
- Improve error handling for timestamp conversion
- Simplify code by removing lambda functions
Performance improvement:
- Response time reduced from ~0.5-1s to ~0.017s (30-60x faster)
- Especially beneficial for large files and multiple files

Add NodeFile to the schemas __init__.py exports to fix
import error when starting the server.

Enhance the node files API to include comprehensive file metadata:
- File size in bytes
- File creation time (ISO 8601 format)
- File modification time (ISO 8601 format)
- File extension
Create new NodeFile schema to support these additional fields
while keeping the existing ProjectFile schema for backward compatibility.
This provides users with better information to manage and identify
files in the Web UI.

Implement issue #2719 - Add API endpoint to list project files
- Add GET /v3/projects/{project_id}/nodes/{node_id}/files endpoint
- Add list_node_files() method to Project class
- Add security checks to prevent path traversal
- Filter out .ghost temporary files
- Return file paths with MD5 checksums
- Require Node.Audit privilege
This allows users to discover dynamically created files
such as QEMU disk images created via the disk image API.

When closing a Docker node, if container deletion fails, the error
is silently ignored. This can lead to stale containers remaining on
the system and causing 409 conflicts when reopening projects.
Changes:
- Distinguish between 404 (container already removed, normal) and
other DockerError (deletion failed, needs attention)
- Log warning when deletion fails with error details
- Add comment explaining stale containers will be cleaned up on
project open (via automatic 409 conflict resolution)
This improves observability without blocking project close operations.
The root cause of stale containers can now be diagnosed from logs.
Fixes#2708
