Use /proc/meminfo MemAvailable instead of sysinfo freeram to properly account for reclaimable cache. Now matches free -h output accurately.

Update: uses |
Query running processes to sum actual GPU memory usage instead of reporting system-wide memory consumption (MemTotal - MemAvailable).

Detect and handle NVIDIA GPUs with unified memory architecture (e.g., GB10) that use system RAM. When
nvmlDeviceGetMemoryInfofails or returns zero memory, fall back to querying system memory viasysinfo()to report total, used, and free memory statistics.This approach mirrors the existing unified memory handling for Apple M1/M2 GPUs and enables proper memory monitoring for NVIDIA GPUs with unified memory.
