fix(spec): the forced-replica D3 entry states its ruling in words, not a tracker number

The reason of turso-config-forced-replica-without-sync-url-refused, the
text os migrate meta prints under why:, opened with a tracker number.
It now says what was decided and why: a replica is defined by its
remote, the ruling weighed refusing the shape against documenting a
replica with no remote as a local mode, and refused it, because with
no remote there is no replica mode to document. The id, surface,
replacement, acceptanceCriteria and the ADR-0087 registration are
unchanged. registry.ts regenerated by gen:migration-registry.
