Replace in-file bootstrap logic with package-level constructors in `run`:
- use `config.Load()` instead of local env parsing/AppConfig helpers
- use `store.Open()` and `web.New()` for persistence and app wiring
- rename local store variable to `benchmarkStore` for clarity
This centralizes startup concerns in dedicated modules, reducing `main.go` boilerplate and improving maintainability.refactor(main): delegate setup to config, store, and web packages
