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.

bbf4510d9d musescore+mixxx: 5-MOAD scan; 2 musescore defects, mixxx CLEAN
musescore-0001: CWE-407 pastedHarmony dedup uses std::vector+std::find
  O(A*H) in Read400/Read410/Read460::pasteStaff; fix: unordered_set O(A).
  100.5x op-count speedup at H=200 harmonies pasted. 1/1 PASS.

musescore-0002: CWE-312 OAuth access+refresh tokens logged verbatim via
  LOGD() in AbstractCloudService::onUserAuthorized(); fix: redact values.
  1/1 PASS.

mixxx: all 5 MOADs CLEAN. Only std::find on a 6-item capped list; all
  cache lookups use QHash/QSet O(1); GlobalTrackCache properly mutex-locked;
  no thread_local misuse; no credential values in log calls.
