wave6: knex-0001 flagship + 38-target docgen/webfw/migration scan survey
knex-0001: Migrator#rollback({all:true}) and Migrator#down() filter
allMigrations against completed via .map(name).includes() inside the
filter callback. Per-iter array allocation + linear scan = O(A*C)
real, O(A*C^2) amortized including GC. Fix: hoist Set<name> once,
Set#has = O(1). Bench: 355x at A=C=2000 migrations.
