tooling(pm): re-count the ADR-0087 manifests deferral to six rows across two source files

The `why:` on the `scripts/check-adr-0087-registration.mjs PACKAGE_ROOTS
packages` row priced its deferral at "nine rows across three gates". That
figure counted CI invocation names rather than gate source files, and the tree
has not matched it since the derivation grew a second key: #15127 keyed this
table on the gate source file and folded the invocation twins away.

Measured at the merge base, six rows in the recorded triage carry a manifests
spelling — three roots each under `scripts/check-adr-0087-registration.mjs` and
`scripts/check-skill-compatibility-version.mjs`. Two source files, not three
gates: `check:changeset-gate-self-tests` runs
`check-adr-0087-registration.mjs --self-test`, so it never was a third gate.

Only prose inside that one `why:` moves. The verdict, the spelling, the row key
and both population figures (74 of 5275, 74 of 74) are untouched — the pins
re-measure those — and `node scripts/pm/bare-root-worklist.mjs --self-test`
prints a byte-identical verdict line before and after the change.
