* fix(xsysinfo): read process VRAM without proc children
Kernels without CONFIG_PROC_CHILDREN have no task children file, so
ProcessVRAM dropped every DRM reading. When that file is missing, walk
child processes from /proc/<pid>/stat ppid links instead. Other read
errors still drop the reading.
Fixes#12481

* fix(system): document trusted procfs reads
Scope G304 annotations to paths built from the fixed procfs root,
integer process IDs, and kernel directory entries. These reads accept
no user-controlled path components.
