✍️ Description

Add a new Langflow script set for ProxmoxVED testing:

ct/langflow.sh
install/langflow-install.sh
frontend/public/json/langflow.json

The script follows the standard CT/install/json layout, uses systemd for service management, and supports update flow through the CT script.

Greptile Summary

Adds a complete Langflow script set (CT, install, and JSON) following ProxmoxVED conventions with systemd service management and comprehensive update/rollback logic.

Major changes:

New ct/langflow.sh with sophisticated update logic, health checks, and rollback functionality
New install/langflow-install.sh using uv for Python dependency management with PyTorch CPU-only installation
New frontend/public/json/langflow.json with complete metadata and user warnings about installation time
Uses Python 3.12 virtual environment with configurable concurrency settings for package installation
Implements secure credential generation and proper file permissions for sensitive configuration

Issues found:

One critical error suppression pattern (|| exit) in install/langflow-install.sh:42 that must be removed per project standards

Confidence Score: 4/5

This PR is safe to merge with one small fix required
The implementation is solid with excellent error handling and follows project conventions closely. The only issue is a single line using || exit which violates error handling standards and must be removed. After this fix, the code will be production-ready.
Pay attention to install/langflow-install.sh:42 - remove the || exit pattern before merging

Important Files Changed

Filename	Overview
ct/langflow.sh	New CT script with comprehensive update logic, proper error handling, and rollback functionality - follows all conventions
install/langflow-install.sh	Clean install script with proper structure and dependency handling - one critical error suppression issue found
frontend/public/json/langflow.json	Well-structured JSON metadata with proper schema, logo URL, and comprehensive notes - fully compliant
