Greg Pomerantz 857dfce19f CEF universe verification: 241/295 parsed + component-sum fractions
- cef_universe_run.py: resumable batch over all 295 CEFs ->
  cef_annual_all.json (241 parsed, actual per-share character).
- cef_rank_all.json: 239-fund ranking, actual char x (t5 + 0.4 vol5);
  surfaces FXBY and DPG beyond the original shortlist.
- share fractions now use the component sum as denominator (always
  sum to 1); dist_tot remains the validity gate. Fixes CEE-style
  111% sums when the NAV-identity fallback total is short.
- server watchdog + app CEF tab; RESEARCH.md updated.
