FOLLOW_UP_2.md called out that recovery only covered one intent-driven update
row. Replace that single-case assertion with a table over the ten recovery
rows documented in PLAN.md, spanning Installing, Updating, and Uninstalling
intents across local, staging, and backup directory states.
The cases intentionally use markerless reserved directories while an intent is
present. That pins the contract that the intent log proves Lanspread ownership
during crash recovery, including the crash windows before ownership markers are
dropped. The test still keeps the existing None-intent markerless case separate
so user-owned reserved names remain protected.
Running the larger table in parallel exposed that this module's TempDir helper
could collide on pid plus timestamp paths. Add a local atomic suffix so these
tests stop deleting each other's directories without doing the broader helper
consolidation reserved for the later hygiene phase.
Test Plan:
- git diff --check
- just fmt
- just clippy
- just test
Follow-up-Plan: FOLLOW_UP_2.md
