- Add incremental materialized view (IMMV) support for both Website and Endpoint asset types using pg_ivm extension
- Create asset_search_view IMMV with optimized indexes for host, title, url, headers, body, tech, status_code, and created_at fields
- Create endpoint_search_view IMMV with identical field structure and indexing strategy for endpoint-specific searches
- Extend search_service.py to support asset type routing with VIEW_MAPPING and VALID_ASSET_TYPES configuration
- Add comprehensive field mapping and array field definitions for both asset types
- Implement dual-query execution path in search views to handle website and endpoint searches independently
- Update frontend search components to support asset type filtering and result display
- Add search results table component with improved data presentation and filtering capabilities
- Update installation scripts and Docker configuration for pg_ivm extension deployment
- Add internationalization strings for new search UI elements in English and Chinese
- Consolidate index creation and cleanup logic in migrations for maintainability
- Enable automatic incremental updates on data changes without manual view refresh
- Replace single-sample CPU calculation with two-sample delta method
- Add 0.5 second sleep between CPU stat samples to calculate actual usage
- Parse all 7 CPU time fields (user, nice, sys, idle, iowait, irq, softirq) from /proc/stat
- Calculate CPU percentage as (1 - idle_diff/total_diff) * 100
- Add zero division protection when total_diff is 0
- Fix incorrect CPU usage reporting caused by using cumulative stat values
