DOCFIX-139..141: repo-rename sweep (ipv4->dc-dc) + repo-lint L9 self-reference guard ...

New repo openstack-caracal-dc-dc still had stale operational references to the
source repo it was seeded from (openstack-caracal-ipv4), plus, after the
mechanical fix, hardcoded references to its own new name -- both break on any
future fork/rename. Fixes:

- DOCFIX-139/140: repaired 8 stale clone-path/URL references across the skill
  and 4 runbook RUN blocks; fixed a repo_lint.py Windows path-separator bug
  that silently turned a documented WARN into a FAIL (rel comparison used
  str() instead of as_posix()).
- DOCFIX-141: new repo-lint check L9 fails any script/RUN-block/skill file
  that hardcodes the current repo's own directory name. Narrowed the
  .claude exclusion in repo_lint.py to .claude/worktrees/ only (it was
  blanket-hiding checked-in .claude/skills and .claude/hooks from all
  lint checks). Established a $REPO session-variable convention
  (runbooks/README.md Conventions) and converted the 8 hardcoded paths to
  require it explicitly, fail loud if unset.

repo-lint: 0 fail / 1 documented legacy WARN. tests/repo-lint harness 34/34.
Full details + per-item revert instructions in the two changelogs.

addendum 26: DOCFIX-094 stderr-separation fixes (cloud-assert fail-open closed) + vault snap-track measurements + juju auth-expiry blocker ...

Gauntlet ALL GREEN (32 harnesses; cloud-assert 12/12 incl. new fail-open
proof cases). Read-only vault measurements landed before the juju macaroon
expired; operator needs interactive 'juju login' for the remaining reads.

Revert: per addendum-26 REVERT line.

addendum 25: DOCFIX-093 batch-3 window do-doc + OpenBao research draft + H5 embed + stderr-sweep inventory ...

Operator-away autonomous batch complete (addenda 23-25). Repo-side queue
empty except H4 (main-chat backlog coordination) ; all remaining work is
the operator-present live window per the new do-doc.

Revert: per addendum-25 REVERT line.

addendum 21: DOCFIX-091 tenant onboarding contract (A1 rulings) ...

New docs/tenant-onboarding-contract.md: operator/tenant boundary + rationale,
explicit role table (manager persona, never admin), tenant intake list,
stage dangers, onboarding confirmation set, hardening register H1-H5
(proposals logged, none implemented). v2-DRAFT banner defers to it.

Revert: per addendum-21 REVERT line (doc-only; no cloud state touched).
