Follow-up to 928e244, which stopped configs/ subdirectories being sourced
without a .category marker. That closed the hole; this removes the thing
that fell into it.
storageIndexFile pointed at configs/storage/app_locations. The file's
requirements are only "manager-owned" and "not on a removable disk" —
configs/ satisfies both, which is why I put it there, and it was still
wrong: that tree carries a third property the file violates. sourceScanFiles
SOURCES what it finds under configs/, and sourcing means executing.
The index is a TSV of "<slug><TAB><root>", which bash reads as a command
and its argument. Harmless while no slug matched a real executable. The
row for the app named `libreportal` armed it, because that IS the CLI on
PATH: sourcing ran `libreportal /libreportal-containers`, which re-entered
the scan, which sourced the file again — one process pair per level until
the host OOMed and took the desktop session with it.
It now lives at $system_dir/storage/app_locations, with a one-shot
migration so an install that already has an index keeps knowing where its
apps live rather than silently forgetting. libreportal-ownership
reconciles the new directory, and scan_files.sh gained a note that
configs/storage/ carries no .category on purpose.
scripts/dev/lp-configs-guard-test covers both ends: the index never lands
in configs/, a legacy one migrates, and a file of the exact detonating
shape placed in an unmarked configs/ subdirectory is not executed while a
marked category still loads.
Also wires sourceStorageLocations into the config scan beside
sourceBackupLocations — per-location configs sit at depth 3, below the
generic scan, and need their own walker like the backup ones do.
