Discussion #598, reviving PR #654. The crash-recovery backup written
every 20 minutes went to a single file. If the project was already in a
bad state when a backup ran, that bad state replaced the only recovery
copy.
QETProject now writes the backups in turn to three KAutoSaveFile slots
(BackupGenerations), so one bad write only replaces the oldest
snapshot. Scope is crash recovery only; the opt-in autosave is
unchanged.
After a crash, the recovery prompt groups the snapshots by project and
offers one row per project with a list to pick the snapshot to reopen,
newest selected by default. The snapshots not picked are deleted.
Ported onto current master: writeBackup() keeps the "skip if nothing
changed" check (bugtracker #273) and offerBackupFiles() keeps its place
after the stale-file filter and before the crash report (#901).
Tested with the backup interval shortened to 4 s (test build only):
after three changes, master holds one recovery file, overwritten each
time; this branch holds three, with 4, 5 and 6 folios. After killing
QET, the prompt lists the project; picking the oldest snapshot reopens
4 folios, the default reopens 6. Twice each. ctest 34/34 with and
without KDE Frameworks; the carried-over KAutoSaveFile test passes in
the nokde build.

Another exception: one non-converted code path in projectprintwindow.cpp to be followed-up.
One issue found in the Qt6 code path of diagramview.cpp which has been fixed.
a) using a system provided KF6
b) downloading and compiling KF6
c) using the vendored-in re-creation of the functionality
The behaviour for both Qt5 and Qt6 is steered with the same two variables which were renamed to become version agnostic:
a) BUILD_WITH_KF=ON BUILD_KF=OFF
b) BUILD_WITH_KF=ON BUILD_KF=ON
c) BUILD_WITH_KF=OFF
The version is automatically derived from the chosen Qt major version.
Listing GuiPrivate unconditionally in QET_COMPONENTS breaks the whole
Qt5 configure: find_package(Qt5 COMPONENTS GuiPrivate) looks for a
Qt5GuiPrivateConfig.cmake that has never existed - Qt5 creates the
Qt5::GuiPrivate target implicitly together with Gui. Only Qt6 requires
(and provides) the explicit component.
Move the request into a QT_VERSION_MAJOR-guarded find_package after the
main one, both for the application and for tests/catch (whose targets
link Qt::GuiPrivate via QET_PRIVATE_LIBRARIES). Fixes the msys2/Qt5
Windows CI configure failure:
"Could not find a package configuration file provided by Qt5GuiPrivate".
Verified: Qt 6.11 configure passes and the Qt6::GuiPrivate target is
created (the private-module warning now fires from the guarded call).
The Qt5 path simply no longer requests the component, restoring the
pre-existing implicit behaviour.
Check the QLockFile in staleFiles() before returning a no-KF5 recovery candidate, matching the KAutoSaveFile contract that actively owned autosave files are not stale.
Extend the no-KF5 Catch test so a child process keeps the autosave lock alive while allStaleFiles() runs, then verify recovery after the child is killed.

Add a no-KF5 Catch regression test that leaves a KAutoSaveFile-compatible backup behind from a child process, then verifies stale-file discovery, stale-lock recovery, reading, and cleanup.
