Latte Dock NG 1.2.36

Fixed

Autostart no longer breaks silently when the XDG autostart desktop file disappears (e.g. removed by a package uninstall, emerge --depclean or a failed update): startup now restores it and logs a warning instead of leaving the dock unlaunched on every login.
Autostart updates are staged: the replacement file is copied next to the working entry and swapped in only after a successful copy, so a failed copy can never delete the existing entry.
Autostart failures (missing system desktop file, failed copy) now log warnings instead of failing silently.

New importer-logic and source-contract tests cover the autostart self-heal and staged-update behavior.
The autostart copy-failure test is permission-independent so it behaves identically on user runs and root CI containers.
