  • Add heap_bytes() estimation to all stores (cache, blocklist, query log, SRTT, overrides) with per-record/per-packet heap tracking
  • Add cross-platform process RSS reading (mach_task_basic_info on macOS, sysconf+/proc/self/statm on Linux)
  • Include memory object in /api/stats response with per-component byte counts, total estimated, and process RSS
  • Add 6th stat card (Memory) to dashboard top row showing process RSS headline
  • Add sidebar panel with stacked color bar and component breakdown list

Test plan

  • make all passes (fmt, clippy, audit, build, 111 tests)
  • Start Numa, open dashboard, verify Memory stat card shows RSS
  • Verify sidebar Memory panel shows breakdown with colored bar
  • Curl /stats and confirm memory object in JSON response
  • Test responsive layout at 900px and 700px breakpoints
