Replace @akameco/tsconfig with modern TypeScript configuration

- Remove @akameco/tsconfig dependency
- Create comprehensive modern tsconfig.json with:
  - ES2022 target for Node.js 20+ compatibility
  - Node16 module resolution for ESM support
  - Strict type checking with all recommended rules
  - Declaration and source map generation
  - Proper include/exclude patterns
- All builds, tests, and linting passing with new configuration
- Better type safety and development experience
