test(cli): drop the cardinality from allSixManifests() and its two stale comments

`allSixManifests()` was named for a population of six (5 CLI emissions + the
on-ramp). #16483 retired `os create example`, taking the CLI side to four, so
the helper now harvests five — measured by running it, not by reading it:

  length=5 ids=["os init -t app","os init -t plugin","os init -t empty",
                "os create plugin","npx create-objectstack"]

Nothing went red, because the harvest is derived from the live maps
(`Object.entries(TEMPLATES)` + `Object.entries(templates)`) and no assertion
counts to six. The number lived only in the identifier and in two comments,
which had gone stale in two different senses: the identifier overstated the
TOTAL, and the docblock above it overstated the CLI SUB-count ("the five the
two CLI commands render" — it is four).

The repair is to stop naming a moving fact, not to gate it: a detector for
"identifier's number disagrees with a runtime set" needs either NL parsing or
a hand-maintained map that drifts, which costs more than the p3 it catches.

- `allSixManifests` -> `allScaffolderManifests` (4 sites, all in this file)
- the docblock above it, and the header comment about the control, lose their
  cardinality words rather than trading them for a smaller number

⛔ No count assertion added — that would convert a harmless statement into a
gate needing a hand update on every scaffold change. The derivation path and
the on-ramp firing control are untouched.
