Add pre-commit hook to run lint on staged files

[Copilot]

Adds a platform-independent pre-commit hook that blocks commits with linting errors.

Changes

• Husky setup: Added prepare script to auto-install Git hooks on npm install
• Pre-commit hook: .husky/pre-commit runs npx lint-staged before each commit
• lint-staged config: Only lints staged *.{js,jsx,ts,tsx} files for fast feedback

Usage

After npm install, the hook is automatically active. Commits with ESLint errors will be blocked:

$ git commit -m "my changes"
✖ eslint found some errors. Please fix them and try committing again.

Uses husky (already in devDependencies) which handles cross-platform execution via Git's bundled shell on Windows.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• node-precompiled-binaries.grpc.io
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/durabletask-js/durabletask-js/node_modules/.bin/node-pre-gyp install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

add precommit hook to run lint , if any linting errors, should not commit. the hook should be platform independent and work on different platforms( windows, mac, linux, etc)
