feat: add commitlint and clean up ESLint warnings

Add conventional commit enforcement via commitlint with a commit-msg
husky hook. Suppress no-explicit-any in test files since test mocks
legitimately need type flexibility. Fix npm audit safe vulnerabilities.

- Add commitlint with @commitlint/config-conventional
- Add .husky/commit-msg hook for commit message validation
- Disable no-explicit-any rule for test files in ESLint config
- Add inline eslint-disable for inquirer mixed-type choices array
- Run npm audit fix for resolvable vulnerabilities
