LintabOS 0.3.4

LintabOS 0.3.4 (pre-release)

Bug fix: a real user reported LinWinMod stuck at "Looking for Windows..." forever.

The cause

FilesPage._scan() (and three similar background workers in the same window — _open, _checked, and the Registry
page's _scan_hives) ran their disk/hive discovery in a background thread with no exception handling. If that call
raised — disk enumeration has already failed with a real DiskError in this project's own test logs
(lsblk: /dev/vda: not a block device) — the thread died silently before reaching the GLib.idle_add call that updates
the label, leaving the page stuck on its initial "Looking for Windows…" / "Checking the drive…" / "Opening…" text forever.
Every other scanning window in this codebase (e.g. "Remove LintabOS") already guards against exactly this; this one didn't.

The fix

All four background workers in LinWinMod now catch their own exceptions and show a plain-words message instead of
hanging. A new structural test parses winmod_gui.py's own source and checks that every function calling
GLib.idle_add is wrapped in a try/except, so this bug class is caught if it's ever reintroduced.
