feat: Add Claude Code MCP integration with project-specific memory isolation

[mayankbohra]

Summary

This PR adds native support for Claude Code (Anthropic's official CLI) to OpenMemory via MCP integration, including project-specific memory isolation for better developer experience.

Motivation

• Claude Code is Anthropic's official CLI tool with growing adoption
• Currently no Claude Code support in OpenMemory (only Claude Desktop)
• Developers need project-specific memory isolation when working across multiple codebases
• Leverages existing MCP infrastructure with zero breaking changes

Changes

✅ Completed Tasks

• Add Claude Code to supported MCP clients
• Implement project-specific memory isolation (claude-code-projectname)
• Fix MCP response formatting for Claude Code compatibility
• Create setup script with auto-detection (package.json, git, directory)
• Update UI to handle dynamic project app names
• Add installation documentation
• Pass all linting checks
• Test backward compatibility

Features Added

1. Claude Code Integration

   • Native .mcp.json configuration support
   • Installation helper script
   • UI integration with proper branding

2. Project-Specific Memory Isolation

   • Auto-detects project context
   • Separate memory spaces per project
   • Clear naming: claude-code-projectA, claude-code-projectB

3. Bug Fixes

   • Fixed MCP response validation errors (Pydantic string type)
   • Fixed UI display for dynamic app names
   • Fixed duplicate function name linting issue

Testing

• Tested Claude Code connection with multiple projects
• Verified memory isolation between projects
• Confirmed backward compatibility with existing clients
• All linting checks passed

Documentation

• Updated README with Claude Code setup instructions
• Added .mcp.json.example for reference
• Created comprehensive setup script with help docs

Checklist

• Code follows project conventions
• Documentation updated
• Linting checks passed
• Backward compatible
• No breaking changes

This feature has been in personal use for testing and works reliably.
