Summary

Adds minimal read-only monitoring support for Logitech Bolt receivers (046D:C548).

This allows LinearMouse to discover paired Bolt pointing devices and surface receiver-routed metadata such as name, product ID, serial number, battery level, and connection state where available.

This PR is intentionally scoped as a foundation for Bolt support. Additional Bolt features can be added later after this base receiver monitoring path is reviewed and approved.

Details

• Adds Bolt receiver discovery using Bolt receiver information registers
• Publishes paired Bolt pointing devices through the existing ReceiverLogicalDeviceIdentity model
• Reuses existing routed HID++ metadata reads for friendly name/name and battery level when supported by the paired device
• Adds a Bolt-specific connection notification wait path
• Keeps receiver-routed Logitech reprogrammable controls disabled for Bolt

Non-goals

This PR does not add Bolt support for:

• reprogrammable/special button monitoring
• DPI controls
• pairing or unpairing
• other mutating receiver/device configuration
