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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
