feat(cli): lingo.dev init cursor Command for .cursorrules Setup (#1101)

[SK8-infi]

Add lingo.dev init cursor Command for .cursorrules Setup

Closes #1101

Summary

Adds a new cursor subcommand to lingo.dev init that automates the creation of a .cursorrules file in the project root by copying the template from agents.md.

---

Features & Implementation

• New Command:
  lingo.dev init cursor

  • Generates .cursorrules in your repo root by copying the contents of agents.md (also in the root).

• File Handling:

  • If .cursorrules already exists:
    • Prompts user for overwrite (unless run with --force, which skips prompt and overwrites directly).
    • Skips and notifies if user declines overwrite.
  • Fails with a clear error if agents.md does not exist.

• User Feedback:

  • Success and info spinners/messages for all operations.
  • Clear warning/error output for missing templates or write issues.

• CLI Structure:

  • Refactored init to support subcommands (project for the original logic, cursor as a sibling).
  • All code follows project structure and CLI command registration best practices.

---

Scenarios Tested

• .cursorrules creation when file does not exist.
• Overwriting an existing .cursorrules (prompt and forced mode).
• Skipping overwrite if user answers "No".
• Proper handling and messaging if agents.md is missing.
• Works both interactively and with --force for scripted/non-interactive use.

---

User Experience

• Usage:

  lingo.dev init cursor
  # or, for non-interactive scripting:
  lingo.dev init cursor --force
  

• Output:

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

Ready for review!
This PR brings core parity with expected subcommand conventions and ensures proper rules bootstrapping for the Cursor AI developer workflow.
