v0.4.2

NetAudio 0.4.2 shows the routing matrix inside AI assistants, enrolls DDM devices from the CLI and fixes analog levels and stale reads.

New:

• MCP clients that display MCP Apps views, such as ChatGPT and Claude, can open the interactive routing matrix with show_routing_matrix.
• netaudio ddm enroll DEVICE DOMAIN and netaudio ddm unenroll DEVICE enroll and unenroll Dante Domain Manager devices by name, keeping their configuration.
• With --verify, subscription changes re-read the receiver for up to five seconds, and a change the device accepted but could not report back prints UNCONFIRMED instead of FAILED.
• When a scan without the daemon finds no devices, the CLI names the interfaces it searched and the others to choose with --interface.

Fixes:

• Analog level changes on AVIO-DAI2 and AVIO-DAO2 adapters no longer fail with "lock state is unknown" when the daemon is not running.
• channel gain reads the level from the device instead of the daemon's cache, and the daemon re-reads a device after the CLI changes it, so every client sees the change.
• A DDM device re-enrolled while the daemon runs keeps its managed write permissions, and an unenrolled device no longer reports them.
• Channel inventory accepts pages whose table is larger than their filled rows, follows continuing pages that hold fewer rows than their capacity, and reports a device that advertises transmit channels but lists none as an error instead of an empty list.
