Reasons for making this change

This change adds Cursor editor's ignore patterns to the global gitignore collection because:

1. Security Protection
   These files commonly contain references to sensitive paths (.env, config/secrets/, local debug files) that should never be committed. Unlike .gitignore, they're designed for editor-specific exclusions.

2. Editor Ecosystem Standard
   Cursor (an AI-powered editor growing in Python development) follows VS Code's ignore handling paradigm. We already ignore similar editor files (.vscode/, .idea/).

3. Dual-Purpose Ignore Files
   • .cursorignore: User-specific patterns (equivalent to personal .gitignore)

   • .cursorindexingignore: Controls AI feature access (prevents analysis of generated code/assets)
