Sækja SysManager 1.55.1

[1.55.1] - 2026-07-23
Fixed
- Cleared the last two CodeQL code-quality warnings, bringing the scanner to zero open findings. Neither was a field-visible bug — both paths behaved correctly — but each code shape earned its warning and reads better fixed:
- Temperature service (cs/constant-condition): the one-time disk-name resolution used a double-checked lock (re-testing the cached field inside the semaphore), whose inner re-test CodeQL flags as a constant condition because it doesn't model the cross-thread race the re-test guards. Replaced with a plain "always take the gate, ??= the cache" shape — an uncontended SemaphoreSlim acquire is trivial next to the SMART walk it guards, the race-safety is identical, and the flagged pattern is gone.
- File shredder (cs/local-not-disposed): the exclusive shred stream WAS disposed (via DisposeAsync in a finally), but the manual form isn't recognized by the analyzer. Converted to a scoped await using block — same semantics, including disposing the exclusive FileShare.None handle before the final File.Delete (which would otherwise fail while the handle is held) — a shape both humans and the analyzer read as safe.
