chore: add ESLint configs, lint scripts and pre-commit hook

Add root and per-package .eslintrc.cjs (apps/web, packages/{ai,core,mcp,shared}), add Husky pre-commit hook to run lint-staged, and enable lint / lint:fix scripts across root, apps/web and packages. Update lint-staged to run eslint --fix for TS packages/apps and prettier for other files. Add @codervisor/eslint-config and eslint to devDependencies (and pnpm-lock updates). Also expand turbo task outputs in turbo.json.
