[Quality] KISS: Missing .gitignore file causes node_modules pollution

[newtontech]

实际问题

文件: Repository root (missing .gitignore)

问题:
No .gitignore file exists in the repository. This means:

1. Developers may accidentally commit node_modules/ directory
2. No protection against committing build artifacts, logs, or OS files
3. Violates KISS principle: "Simple things should be simple" - developers shouldn't have to think about what not to commit

改进建议

Create .gitignore file:

# Dependencies
node_modules/
npm-debug.log*
yarn-debug.log*
yarn-error.log*
package-lock.json
yarn.lock

# Build outputs
out/
dist/
build/
*.tgz

# Environment variables
.env
.env.local
.env.*.local

# IDE and editor files
.vscode/
.idea/
*.swp
*.swo
*~
.DS_Store

# Test coverage
coverage/
.nyc_output/

# Electron specific
*.log

为什么重要

• Severity: MEDIUM - Risk of repository pollution
• node_modules can be 500MB+ and should never be committed
• Build artifacts cause merge conflicts and bloat repository
• Simple oversight that causes real problems

优先级

• 高 - 影响系统稳定性/安全性
• 中 - 影响代码质量
• 低 - 改进建议
