The `dedupHomeScenesOn` helper in `data/scope/dedup-workbench-scenes.ts`
existed only to be called once from the v48 Dexie upgrade — outside of
that single usage it was dead code. Inlining the logic directly into
the upgrade callback eliminates a 120-line module + a 220-line test
file (343 lines net) without changing behaviour: the v48 upgrade still
collapses uncustomised "Home" duplicates per (spaceId, name='Home'),
merges openApps, and soft-deletes losers.
Drive-by tightening:
- `seedWorkbenchHomeOn` returns `Promise<void>` instead of
`Promise<boolean>`. The boolean was only consumed by the
post-`reconcileSentinels` dedup pass that already got removed; the
current callers (registry seeder + tests) don't read it. Less
signature surface, fewer assertions in tests.
- `data/scope/per-space-seeds.ts` comment header drops the
plan-internal "Schicht B + C" reference for a plain link to the
cleanup plan. Code-level vocabulary now reads cleanly without the
rollout-sequencing context.
