release-train: develop -> staging

[LukasWodka]

Automated promotion by the release train (RFC-0008 D14). Head is the train-managed release-train/to-staging branch (a mirror of develop), so it never collides with a human PR. Merged only when the fr-gate is green.

Note

Medium Risk
Changes the required conformance contract for multiple repos and branch protection assertions; misalignment would block merges via caller-drift/conformance-gate, but the edits track remediations rather than new policy.

Overview
Updates repo-inventory.yml so the org conformance contract matches measured GitHub reality after recent caller and protection work (backend#2498, .github#332/.github#335).

New repo: Adds a full design-system-v2 entry once the repo had a branch to audit, fixing “active in org but missing from inventory” during live-fleet caller-drift.

Caller flips:rfcs and claude-skills mark code-quality.yml as required (callers on the audit branch). claude-skills arms bugbot-gate.yml as the first org pilot and exempts fr-gate.yml because there is no promotion pipeline and the caller is absent—avoiding a permanently red required row.

Protection:rfcs/develop moves from unprotected exemption to required baseline (quality checks now armed). rfcs/main and claude-skills/main comments are corrected so empty required_checks are justified by measured state, not stale “no code-quality producer” text.

Shared anchors:bugbot_gate_rollout_pending and code_quality_caller_missing drop hand-maintained repo counts and point reviewers at anchored grep to derive who still cites each exemption.

New repo structural cells disagree

This is a second look at once-reviewed code -- it passed per-feature review on the source branch, and has NOT had functional review yet (that happens on staging). Fix forward on develop if any is real.

What the train did with each:

• New repo structural cells disagree - filed as https://github.com/tracebloc/backend/issues/2512, thread resolved by the train.
