docs: add CLAUDE.md for AI assistant context

[cursor]

Summary

This PR adds a CLAUDE.md file to the repository to provide context for Claude and other AI coding assistants when working on the Plane documentation project.

What changed

• Created CLAUDE.md with comprehensive project context including:
  • Project overview and tech stack
  • Essential pnpm commands
  • Development workflow and branch strategy
  • Content guidelines for Markdown files
  • Directory structure reference
  • Important constraints and best practices
  • Testing procedures

Why this change

The repository already has AGENTS.md (an open standard for AI agents), but was missing CLAUDE.md, which is specifically read by Claude Code and Claude-based tools. According to 2026 best practices, many projects include both files to ensure compatibility with different AI coding assistants.

Having both files ensures:

• Claude-specific tools can access project context immediately
• Consistent coding standards and conventions are followed
• AI assistants understand the project structure and constraints
• Development workflows are properly documented for automated tools
