fix(storm-measure): check BOTH halves of the activation SC, not just the count delta

Browse source 
The SC asks two things of an effort: high run: that it discovered at least
one dimension AND that the dimension list in the output brief is a TRUE
SUPERSET of the interview-derived ones. activationCheck computed
dimensions - dimensions_baseline >= 1 and returned ok on that alone. A
count delta says nothing about membership: a run that dropped two
interview dimensions and appended three discovered ones is +1 and passed
the check while violating the second half outright. Supersetness was
asserted only by Phase 4.5's prose contract that discovery appends -
nothing read it.

The stats record cannot carry the dimension names that would show it
directly: names are free prose, and lib/exporters/field-allowlist.mjs
denies prose by omission (question, project_dir, brief_path are already
excluded for that reason). So the run attests membership with
dimensions_baseline_preserved, a boolean set in a new Phase 4.5 step 5,
and the gate refuses to call activation OK without it. An ABSENT
attestation fails rather than falling back to the old count-only rule -
otherwise legacy rows would keep passing on the defect.

Producer side wired end to end: the record format, the measurement-fields
prose (five fields -> six), the exporter allowlist, the jsonl-schemas
fixture row, and the --activation-check comment in
docs/storm-measurement.md.

Review finding d2786604458207a5a73478cdcb6a54bbdb92141d (MINOR).

* SC activation check: did the most recent `effort: high` run actually discover

* The SC asks two things of an `effort: high` run: that it discovered at least
* one dimension, AND that the dimension list in the output brief is a TRUE
* SUPERSET of the interview-derived ones. This function used to check only
* `dimensions - dimensions_baseline >= 1`, which is a count delta and says
* nothing about membership — a run that dropped two interview dimensions and
* added three discovered ones passed while violating the second half.
* Supersetness was asserted only by Phase 4.5's prose contract that discovery
* APPENDS; nothing read it.
*
* The record cannot carry the dimension names: names are free prose, and
* lib/exporters/field-allowlist.mjs denies prose by omission. So the run attests
* membership with `dimensions_baseline_preserved`, a low-cardinality boolean set
* in Phase 4.5, and this gate refuses to call activation OK without it. An
* ABSENT attestation is not an attestation — legacy rows fail here rather than
* passing on the old count-only rule.
