feat(tooling): add lint-staged with Prettier + ESLint on pre-commit
- Install prettier, lint-staged, eslint-config-prettier
- Configure lint-staged in package.json: Prettier write on staged files, ESLint check on .ts/.html
- Add eslint-config-prettier to .eslintrc.json extends to disable formatting rules that conflict with Prettier
- Configure no-unused-vars to allow _ prefix (intentional destructuring pattern)
- Replace manual prettier/git update-index lines in pre-commit hook with npx lint-staged
- Fix pre-existing ESLint errors: remove unused imports in herowars-guildraid, fix useless escapes in middleware.ts, fix eslint-disable comment in utilityTypes.ts
