🚀 HTTP Transport Default & crawl4ai 0.7.1 Update

This PR implements the latest changes documented in JOURNAL.md to enhance CPU container functionality and upgrade to the latest crawl4ai version.

📋 Changes Summary

HTTP Transport Configuration:

• Updated CPU containers to use HTTP transport by default (instead of STDIO)
• Added environment variables: MCP_TRANSPORT=http, MCP_HOST=0.0.0.0, MCP_PORT=8000
• Container now exposes port 8000 for HTTP access
• Provides persistent operation instead of immediate exit

crawl4ai 0.7.1 Upgrade:

• Upgraded from >=0.3.0 to ==0.7.1 for latest features and bug fixes
• Ensures consistent version usage across deployments

RunPod Import Error Resolution:

• Fixed "Import 'runpod' could not be resolved" Pylance error
• Added conditional imports with proper error handling for local development
• Updated IDE configuration to suppress expected missing import warnings
• Enhanced Dockerfile.runpod with RunPod dependencies

🔧 Technical Changes

Files Modified:

• Dockerfile.cpu - Updated crawl4ai version and HTTP transport configuration
• docker-compose.cpu.yml - Added HTTP transport environment variables
• runpod_handler.py - Added conditional imports and error handling
• requirements-runpod.txt - Updated with runpod>=1.7.13
• Dockerfile.runpod - Enhanced with RunPod dependencies
• pyrightconfig.json - Configured missing import suppression
• .vscode/settings.json - Fixed configuration conflicts
• JOURNAL.md - Comprehensive documentation of all changes

Configuration Updates:

• Transport Mode: Changed from STDIO (exiting immediately) to HTTP (persistent)
• Port Exposure: Container now exposes port 8000 for HTTP access
• Environment Variables: Added MCP_TRANSPORT, MCP_HOST, MCP_PORT for HTTP mode
• RunPod Integration: Added proper serverless deployment configuration

✅ Benefits

• Persistent Operation: CPU containers stay running on port 8000
• Local Development: Easy HTTP access at http://localhost:8000
• Latest Features: Access to crawl4ai 0.7.1 improvements and bug fixes
• Better UX: More intuitive server behavior for users expecting persistent operation
• Clean Development: No more Pylance warnings for expected missing dependencies
• Serverless Ready: Full RunPod serverless deployment support

🧪 Testing

• CPU containers build successfully
• HTTP transport configuration verified
• Port 8000 accessibility confirmed
• Persistent operation validated
• RunPod import error resolved
• No regression in existing functionality

This change aligns with the engineering journal entries from 2025-07-21 and provides significant improvements for both local development workflows and serverless deployment.
