SysManager 1.51.11

[1.51.11] - 2026-06-30

Fixed

• A native string buffer was leaked on every Known-Folder lookup. The Downloads/Documents/Desktop/Pictures/Music/Videos path resolver marshalled the Win32 result as a managed string but never freed the underlying COM-allocated buffer; it now takes the raw pointer and frees it, so repeated lookups (cleanup scans, etc.) no longer leak memory.
• Two power-plan changes could corrupt a concurrent power-query's output. The power-plan/processor-state/hibernation writers shared the same process runner as the readers that parse powercfg output, but ran without the reader's serialization gate; a write running during a read could interleave the output stream. The writers now take the same gate.
• Listing installed apps could drop or corrupt a line under a thread race. The winget-list output collector used a plain list that both the stdout and stderr reader threads wrote to concurrently; it now uses a thread-safe queue, matching the upgrade-list path.
