Setup pre-commit hooks and Copilot CI workflow

[Copilot]

Enforces code quality gates before commits and in CI for Copilot-generated PRs.

Pre-commit Hook

• Husky + lint-staged runs Prettier and ESLint on staged files only
• Full test suite runs before commit succeeds
• prepare script auto-installs hooks on npm install

CI Workflow

.github/workflows/copilot.yml runs on PRs and copilot/** branches:

• Format check (Prettier)
• Lint (ESLint)
• Tests (Jest)
• Build (Vite)

Configuration

Prettier (.prettierrc):

• Standard settings: semi-colons, trailing commas, double quotes, 80-width
• Excludes dist, node_modules, coverage, generated proto files

lint-staged (in package.json):

{
  "*.{ts,tsx}": ["prettier --write", "eslint --fix"],
  "*.{json,md,yml,yaml}": ["prettier --write"]
}

Scripts

npm run format         # Format all files
npm run format:check   # Verify formatting

Formatted existing codebase to establish baseline.

Original prompt

Please setup git pre-commit hook in the project and github actions for copilot.
test, lint and format should pass before commit.
