Manager, Hand, and metadata

Manager owns discovery, connection, transport reuse, and global shutdown. Python uses Manager, C++ uses revo3::Manager, and C uses revo3_manager_*.

Hand represents one connected device and exposes DeviceInfo, FirmwareInfo, JointLayout, slave ID, runtime statistics, and all capability domains.

Type	Content
DetectedDevice	Port, protocol, slave ID, model, and serial number during discovery
DeviceInfo	Serial number, model, side, hardware revision, and module serials
FirmwareInfo	Controller, motor, and touch firmware versions
JointLayout	Layout ID, version, and joint count

Only override a model when the BOM or validation record confirms it. Use the official API specification for exact signatures.
