docs(spec): re-anchor the dead tracker citations in the manifest, dataset and permission liveness ledgers to the commits that decided them

134 note sites across three ledgers cited GitHub issues that answer 404.
Each now names the commit that decided it (the ADR/ruling-record-else-commit
order), and says the decision in words where the number alone carried it.
Note strings only: every row's status, evidence, proof and verifiedAt is
unchanged.

+
+The `manifest`, `dataset` and `permission` liveness ledgers cite the commit that decided each note instead of a tracker number that no longer resolves
+
+Clause-②: no
+
+Notes in these three ledgers named GitHub issues that no longer exist, so a reader could
+not tell why a row carries its verdict. Each such note now names the commit that made the
+decision and, where the number alone carried the meaning, says what was decided. The
+`liveness/` ledgers ship in this package's tarball, which is why this is a release note at
+all. Note text only: no row's status, evidence, proof or date changes, and no schema,
+export or runtime behaviour changes.
