Add ESLint to all packages and reorganize CLI

ESLint:
- Add @macalinao/eslint-config and eslint to all packages/apps
- Add lint scripts to all package.json files
- Create eslint.config.js for all apps
- Add lint task to turbo.json
- Add @macalinao/eslint-config and @types/bun to catalog

Biome:
- Exclude docs/ from biome checks

CLI Reorganization:
- Restructure CLI to use route maps with one command per file
- Move commands to routes/ directory structure
- Use func property instead of async loaders
- Route maps in _command.ts files for each directory

Environment:
- Use Bun.env instead of process.env for env vars
- Add DATABASE_URL and PORT to turbo.json globalEnv

Lint Fixes:
- Fix nullish coalescing operator usage
- Update deprecated Zod API (z.email() instead of .string().email())
- Fix import sorting
