fix(manifests): repair four missing + one dangling AI-manifest parent pointer

Five nested AI-manifests had parent pointers that did not resolve (caught by
the PR #42 tidy's manifest-integrity audit, but pre-existing and out of that
PR's scope):

  examples/0.1-AI-MANIFEST.a2ml            one-line stub -> add META + AI_MANIFEST
  .github/0.1-AI-MANIFEST.a2ml             one-line stub -> add META + AI_MANIFEST
  verification/tests/0.2-AI-MANIFEST.a2ml  one-line stub -> add META (level 2)
  container/0.1-AI-MANIFEST.a2ml           full body, no level/parent -> add them
  docs/governance/0.1-AI-MANIFEST.a2ml     parent pointed at non-existent
                                           ../0-AI-MANIFEST.a2ml -> repoint to the
                                           docs pillar ../0.1-AI-MANIFEST.a2ml

Every manifest parent pointer in the repo now resolves.

NOTE (flagged, not fixed here): the docs/governance/ subtree uses an off-by-one
numbering — it calls itself a top-level "governance-pillar" (level 1) while
sitting under docs/, and its children are numbered relative to it. Normalizing
that subtree (or promoting governance to a repo-root pillar) is a separate
structural decision; this commit only makes the dangling pointer resolve.
