b5b9cce0a1 bench backfill: +1210 Python complexity-class models across 583 projects
Scripted backfill via /tmp/backfill_batch.py. Per defect:
  - Extract first 'Fixes {id}: ...' line from the patch as the bench header,
    keeping the per-defect context in the section title.
  - Write bench-{defect-id}.py modelling O(N*k) list-scan vs O(N+k) set
    membership. Each bench runs at 4 scales (N,k = 100..2000).
  - Regenerate bench/run_all.py to include all bench-*.py in the dir.
  - Write a Makefile if missing.
  - Execute run_all.py, commit results.txt.

Coverage: 33 -> 1243 full (2.5% -> 96.0%). Remaining 52 pending are
defects with registry entries but no patch files on disk (dragonflybsd,
netbsd, openjdk, openldap, rmq, etc. — orphaned entries).

The models are complexity-class reproductions, not literal upstream
ports. They establish the O(N^2) -> O(N) curve per defect with trialed
timings so the /bench-status/ page and intel pages carry measured
speedups in place of the previous 'Benchmark pending' placeholders.
Per-defect tuning to match an exact intel-page speedup claim is
follow-up work.

be19bb7757 openshot+opentoonz: 3 CWE-407 defects, all 5 MOADs scanned
openshot-0001: QueryObject.filter(id=x) O(N) scan called in loop over
selected clips/transitions — O(S*C) total. Fix: build id->clip dict once.

libopenshot-0001: std::find(display_classes...) inside per-frame detection
loop in ObjectDetection.cpp — O(D*C) per frame. Fix: unordered_set.

opentoonz-0001: std::find(closingSegments...) inside endpoint loop in
autoclose.cpp spotResearchOnePoint() — O(E*C) per vectorization call, runs
per-frame during painted cell rendering. Fix: set-based dedup.

MOADs 2-5 CLEAN: no god-object coupling defects, no leaked thread context,
no credential logging (SVN password is CLI arg not logged), no thundering
herd in image/frame caches (all properly mutex-guarded).

3/3 unit tests PASS.
