PocketFab Secure Intercom — Ubuntu Rev-6.1

For Ubuntu 24.04 x86_64 with a graphical desktop and PipeWire audio.
Close Secure Intercom, extract this ZIP, open a terminal in the extracted
folder, and run:

    sh install.sh

Run as your normal desktop user, without sudo. Unlock your login keyring
when prompted. Open PocketFab Secure Intercom from the application menu.

Existing activation, device identity, contacts and settings are retained.
The installer keeps the previous application folder for rollback.
New users must obtain an activation code through the existing PocketFab
registration process and use Complete setup in the application.

The microphone and headphone selection follows Ubuntu Sound Settings.
Ringer output is selected separately within Secure Intercom.

This package contains the exact application files accepted on pocketfab4090.
The separate R6 update-check and renewal helper UI is not present in this
accepted application. Existing R6 automatic update checks do not recognize
fractional revision R6.1; download and install this release manually.
