ci(spec-shape-gate): register the retired visibility key's test-project diagnostic too

objectui's react type-check chains its test project after the source
project, so the scheduled run's red at SchemaRenderer.tsx:1945 kept the
test project from ever compiling. Compiled locally (objectui main
f78efdd1e3 against the spec built from 570f01d), that project reds once
more on the same retirement: SchemaRenderer.expressions.test.tsx:171 TS2322,
a string authored into the page component's tombstoned visibility. Register
it under the same entry so the gate does not red on it once the source
project goes green ahead of the test.

One entry per retirement, written by the accepting seat when the downstream (objectui) card is filed, deleted when that card closes. Every entry carries exactly: retired, objectstack_pr, objectstack_commit (40-hex merge commit), downstream_card (owner/repo#N), registered_at (YYYY-MM-DD), matches (non-empty; each pattern names a repo-relative objectui `file` -- `*` within a segment, `**` across -- plus at least one of `code` (TS<digits>) or `message` (substring)).
