- INSTALL.md: bump the setup filename to 0.3.0; add an end-user section
on text chat + sending photos/files (inline images, file chips,
Save/Download, 25 MB cap, session-only); note that both ends must run
the same version under "won't connect".
- README.md: add a Version compatibility section (installer version
tracks Cargo; a 0.x MINOR bump is a breaking wire change so everyone
must reinstall; 0.3.0 can't talk to 0.2.x).

A non-technical walkthrough to send alongside the installer: covers the
SmartScreen "unknown publisher" warning, the firewall/desktop-shortcut
checkboxes, and joining/creating a call via room tickets. Uses the actual UI
labels (Join Room / Create New Room / Copy Ticket / Leave Room).
