Add `lingo.dev init cursor` command for .cursorrules setup

[maxprilutskiy]

Summary

Add a new cursor subcommand to lingo.dev init that generates a .cursorrules file by copying instructions from packages/cli/agents.md.

Requirements

• Create .cursorrules file by copying contents from packages/cli/agents.md
• Handle existing .cursorrules files (prompt to overwrite or skip)

User Experience

$ lingo.dev init cursor
✓ Created .cursorrules

📝 .cursorrules has been created with i18n-specific instructions for Cursor AI.

Implementation Details

File Creation

• Read contents from packages/cli/agents.md
• Write contents to .cursorrules in project root
• No customization or modification of content

Dependencies

• Depends on Add CLI commands reference documentation for agent integration #1099 (Create packages/cli/agents.md file)

Edge Cases

• Repository with existing .cursorrules file
• Missing packages/cli/agents.md template

Analysis and Implementation Plan

I'll implement the lingo.dev init cursor command as requested. This will create a .cursorrules file by copying contents from packages/cli/agents.md.

Todo List

• Execute mandatory protocol steps (contributor analysis, codebase exploration, labeling)
• Explore CLI codebase structure to understand init commands
• Check if packages/cli/agents.md exists (dependency from Add CLI commands reference documentation for agent integration #1099)
• Create temporary agents.md for testing (since Add CLI commands reference documentation for agent integration #1099 dependency is missing)
• Restructure init command to support subcommands
• Implement the cursor subcommand
• Add file existence handling (prompt to overwrite/skip)
• Test the implementation
• Run linting/type checking
• Commit and push changes
• Provide PR creation link

Analysis Results

CLI Structure Understanding:

• Subcommands use .addCommand() pattern (seen in show/config commands)
• Individual subcommands use new Command().name("subcommand")
• Current init.ts is a single command, needs restructuring to support subcommands

Plan:

1. Create temporary agents.md with placeholder content for testing
2. Restructure init command to have subcommands (breaking change)
3. Move current init logic to a default subcommand or keep as main command
4. Add cursor subcommand implementation

This is similar to #1100 - check that for context
