• Identify false sharing risks in concurrent code
• Cache line breakdown in memory layout panel

Workspace Memory Analyzer

• New command: \Go: Analyze Workspace Memory Layout\
• Scans all Go files for optimization opportunities
• Ranks structs by potential memory savings
• Highlights cache line boundary issues across codebase
