feat: add support for regular DNS on port 53 (#48)

* feat: add support for regular DNS on port 53

*   Implement standard UDP and TCP DNS listeners alongside the existing
    DoT service.
*   Add a new `--dns-port` flag (defaulting to 53) to allow
    configuration of the regular DNS interface.
*   Refactor server lifecycle management using `errgroup` to
    concurrently run HTTP, UDP DNS, TCP DNS, and DoT listeners.
*   Update `GEMINI.md` and `README.md` with instructions for testing
    both regular DNS and DoT in production and development modes.

* refactor: unify DNS and DoT server startup

Refactor the server initialization to reduce duplication and improve
readability.

- Consolidate **DoT** server logic into a single goroutine.
- Use integer variables for port logging to avoid redundant formatting.
- Rename the `errgroup` variable from `g` to `group`.

```mermaid
graph TD
    A[RunServer] --> B{app.DevMode?}
    B -->|Yes| C[Set Dev Ports]
    B -->|No| D[Set Standard Ports]
    C & D --> E[Start HTTP, UDP, TCP Servers]
    C & D --> F[Start DoT Goroutine]
    F --> G{app.DevMode?}
    G -->|Yes| H[Network: tcp]
    G -->|No| I[Network: tcp-tls + Cert Config]
```

* feat: add dot-port flag and simplify port logic

- Add a new `--dot-port` flag to customize the DoT listening port.
- Centralize port initialization in `main.go` to separate CLI concerns
  from internal application logic.
- Improve `DEV_MODE` behavior by allowing explicit port overrides via
  command-line arguments.
