Track Specification: Performance Dashboard (performance_dashboard_20260306)

Overview

Expand performance metrics panel with CPU/RAM usage, frame time, input lag with historical graphs. Uses existing performance_monitor.py which has basic metrics but no visualization.

Architectural Constraints

• 60fps Constraint: Metrics collection MUST NOT impact frame rate.
• Thread Safety: Cross-thread metrics MUST use proper synchronization.

Functional Requirements

• CPU/RAM Graphs: Display rolling CPU and RAM usage over time.
• Frame Time: Show frame time histogram.
• Input Lag: Track and display input-to-response latency.
• Historical Data: Maintain rolling window of metrics history.

Acceptance Criteria

• CPU graph shows rolling history.
• RAM graph shows rolling history.
• Frame time histogram displays.
• Input lag metrics tracked.
• Uses existing performance_monitor.py.
