Missing runtime dependencies in Home Assistant Bluetooth dependency chain

### The problem

### Description

A clean installation of Home Assistant does not install all dependencies required when importing the Bluetooth stack and its hard dependencies.

The affected dependency chain includes:
```
bluetooth → usb → serialx
```
During import, dependencies such as aioesphomeapi and aiohasupervisor are required, but they are not declared transitively. As a result, compatibility checks that install Home Assistant and then import the Bluetooth stack fail with ModuleNotFoundError.

### Reproduction

```bash
python -m pip install homeassistant
python -c "import homeassistant.components.bluetooth"
```

Alternatively, inspect the manifests for bluetooth, bluetooth_adapters, usb, and their dependencies, then import the Bluetooth integration in a clean environment.

### Workaround

Install the missing packages manually:

```bash
python -m pip install aioesphomeapi aiohasupervisor
```

### Expected behavior

Installing Home Assistant should install all runtime dependencies required to import its Bluetooth integration and dependency chain.

### Environment

- Home Assistant: affected stable/latest release
- Python: 3.14
- Installation: clean pip environment

### Additional information

_No response_

Start by inspecting the manifests for bluetooth, bluetooth_adapters, usb, and their dependencies, then reproduce the failure in a clean environment with `python -m pip install homeassistant` followed by importing `homeassistant.components.bluetooth`. Done means the clean installation includes the runtime dependencies and the Bluetooth integration imports without ModuleNotFoundError.
