Add pre-commit hooks for lint and format commands

[bhouston]

Overview

Implement pre-commit hooks to automatically run the project's lint and format commands before each commit. This will help maintain code quality and consistency throughout the codebase.

Implementation Plan

1. Install required dependencies:

   pnpm add -D husky lint-staged

2. Add configuration to package.json:

   "lint-staged": {
     "*.{js,jsx,ts,tsx}": [
       "pnpm lint",
       "pnpm format"
     ]
   }

3. Initialize husky:

   pnpm husky install

4. Add a prepare script to package.json to ensure husky is installed on npm install:

   "scripts": {
     "prepare": "husky install"
   }

5. Create a pre-commit hook:

   pnpm husky add .husky/pre-commit "pnpm lint-staged"

6. Add documentation in CONTRIBUTING.md about the pre-commit hooks

Benefits

• Ensures all committed code meets the project's style guidelines
• Prevents formatting inconsistencies
• Catches linting errors before they're committed
• Reduces the need for style-related code review comments

Additional Notes

• We should consider only running lint/format on staged files to improve performance
• We may want to make the hooks skippable with a flag for emergency situations
