self-review 2026-07-26: heartbeat wm_churn + wm_top0_wm; fix streak counting on empty id

Browse Source 
- wm_churn: count of top-5 WM ids absent from previous beat — separates
  'one stuck node' from 'whole WM frozen' without hand-correlating ISEs.
- wm_top0_wm: leader's weight; a frozen anchor reads as a constant here.
- Streak guard: before the runtime emitted id in wm_top JSON,
  json_get(...,"id") was always empty and the streak incremented on
  ""=="" every beat — wm_top0_streak measured uptime, not fixation.
  Empty id now resets the streak to 0.
