FN-7666: record weekly test-velocity regression finding (gate 7.7s -> 36.3s)
Narrative: update the 2026-W28 test-velocity baseline report with the newly measured merge-gate/changed-test wall-time regression and document root-cause attribution.
- Bump baseline cycle to 2026-W28 (captured 2026-07-08T09:30:50.606Z)
- Update headline metrics table: gate 7.7s -> 36.3s (+28.6s), boot smoke 17.4s -> 25.3s (+7.9s), pnpm test 9.3s -> 43.4s (+34.0s), quarantine count unchanged at 1
- Add FN-7666 finding note attributing the regression to ~4,305 new re-exported source lines across 14 modules pulled through the @fusion/core / @fusion/engine barrels, inflating per-fork import/transform cost across the 18 curated engine-core gate files; confirms it is a genuine regression (not cache/env noise) via cold-vs-warm reruns; files follow-up FN-7667 for the barrel-decoupling fix
- Update weekly history table (previous/latest/delta rows) and the #leads post text block
- Append new row capturing this week's measurements to scripts/test-velocity-history.json
