Implement real-time process monitoring and fix UI hardcoded data
This commit addresses several key issues identified during development: Major Changes: - Replace hardcoded top CPU/RAM process display with real system data - Add intelligent process monitoring to CpuCollector using ps command - Fix disk metrics permission issues in systemd collector - Optimize service collection to focus on status, memory, and disk only - Update dashboard widgets to display live process information Process Monitoring Implementation: - Added collect_top_cpu_process() and collect_top_ram_process() methods - Implemented ps-based monitoring with accurate CPU percentages - Added filtering to prevent self-monitoring artifacts (ps commands) - Enhanced error handling and validation for process data - Dashboard now shows realistic values like "claude (PID 2974) 11.0%" Service Collection Optimization: - Removed CPU monitoring from systemd collector for efficiency - Enhanced service directory permission error logging - Simplified services widget to show essential metrics only - Fixed service-to-directory mapping accuracy UI and Dashboard Improvements: - Reorganized dashboard layout with btop-inspired multi-panel design - Updated system panel to include real top CPU/RAM process display - Enhanced widget formatting and data presentation - Removed placeholder/hardcoded data throughout the interface Technical Details: - Updated agent/src/collectors/cpu.rs with process monitoring - Modified dashboard/src/ui/mod.rs for real-time process display - Enhanced systemd collector error handling and disk metrics - Updated CLAUDE.md documentation with implementation details
