## Summary
Follow-up to #20464. That PR added `--light` to the preview env seed
command but left the `--` between `yarn command:prod` and the script
args. After yarn strips its own `--`, nest-commander still sees `argv:
[..., '--', 'workspace:seed:dev', '--light']`. Commander.js treats `--`
as the end-of-options marker, so `--light` is parsed as a positional arg
and silently ignored — the seed runs in full mode (Apple + YCombinator +
Empty3 + Empty4) and Empty4 still ends up as the default workspace.
## Evidence
In the preview run on `f706cc052b` (which had #20464's `--light` flag),
the seed step took only ~40s but the `GqlTypeGenerator` log emits four
regenerations across two workspaces with custom objects:
- 28 standard → 28 + 5 custom (`rocket, surveyResult, employmentHistory,
petCareAgreement, pet`) — matches Apple
- 28 standard → 28 + 1 custom (`surveyResult`) — matches YCombinator
With `--light` actually applied, `getLightConfig` returns `{ objects:
[], fields: [] }` so no custom objects should be generated.
The working `twenty-app-dev` invocation in
`packages/twenty-docker/twenty-app-dev/rootfs/etc/s6-overlay/scripts/init-db.sh:66`
is `yarn command:prod workspace:seed:dev --light` — no `--`. Matching
that fixes it.
## Test plan
- [ ] Trigger the preview-app label on a PR, confirm only the Apple
workspace is created and `tim@apple.dev` signs in there
- [ ] Confirm the seed step still passes
