Improve .gitignore with additional patterns

[MiWeiss]

Summary

• Enhanced .gitignore with commonly needed patterns
• Organized entries by category with comments
• Prevents accidental commits of sensitive and temporary files

Changes Made

Added Patterns

General logs:

• *.log - All log files (supplements existing npm-debug.log)

Environment files:

• .env and .env.* - Environment configuration files (may contain secrets)
• !.env.example - Explicitly allow example env files

Editor files:

• *.swp, *.swo - Vim swap files
• *~ - Backup files from various editors

Python:

• *.pyc, *.pyo - Python bytecode files
• .python-version - pyenv version file

OS files:

• .DS_Store - macOS folder metadata
• Thumbs.db - Windows thumbnail cache

Organization

Added comments to group related patterns:

• Node
• Build output
• Environment files
• IDE and editor files
• Python
• Browser extension
• OS files
• Jekyll

Why This Matters

Security:

• .env files often contain API keys and secrets
• Prevents accidental exposure of sensitive data

Collaboration:

• OS-specific files (.DS_Store, Thumbs.db) clutter repos
• Editor swap files cause merge conflicts
• Python bytecode (.pyc) shouldn't be version controlled

Cleanliness:

• Reduces clutter in git status
• Prevents unnecessary files in commits
• Makes repo more professional

Common Scenarios Prevented

1. Developer on macOS accidentally commits .DS_Store files
2. Developer using Vim leaves .swp files that cause conflicts
3. .env file with production secrets gets committed
4. Python cache files pollute the repo

Test Plan

• Verify existing ignored files still work
• Check that new patterns correctly ignore test files
• Confirm .env.example is still tracked (if it exists)
