build(deps): bump js-yaml and antora in /antora

[dependabot]

Bumps js-yaml to 5.4.1 and updates ancestor dependency antora. These dependencies need to be updated together.

Updates js-yaml from 4.1.0 to 5.4.1

Changelog

Sourced from js-yaml's changelog.

[5.4.1] - 2026-08-26

Changed

• Hard-limit merge sequence size to 100.

Security

• Count empty mappings in merge sequences toward maxTotalMergeKeys to limit CPU usage, #797.

[5.4.0] - 2026-08-25

Added

• Added the scalarStyleRules dumper option to customize string formatting. See Scalar styling for details.

Changed

• [breaking] Flattened the low-level AST node style representation. Scalar and collection nodes now use SCALAR_STYLE and COLLECTION_STYLE values; explicit tags use the separate tagged property. Alias nodes now contain only kind and anchor. This only affects code that directly constructs or edits AST nodes.
• [breaking] The sortKeys option was rewritten using AST mutation to avoid side effects.
• Reworked scalar style selection. This can change formatting without changing loaded values; in particular, whitespace-only strings are now double-quoted.

Fixed

• Accept a byte order mark at the start of each document in a stream, #791.
• Produce valid flow mappings with quoteFlowKeys and flowSkipColonSpace, including alias and property-only keys, #786.
• Preserve empty scalar items when converting block sequences to flow style.
• Do not apply the 1024-character simple-key limit to flow mapping keys.
• Count Unicode code points, rather than UTF-16 code units, for the 1024-character simple-key limit.
• Add an explicit document-end marker after keep-chomped block scalars when needed to preserve trailing newlines.

[5.3.0] - 2026-08-14

This release focuses on reworking the documentation and making small architectural improvements before moving forward.

Added

• Added completely new documentation.
• Exported DUMP_SCHEMA, the default schema used by the dumper.
• Added YAMLException.throwAt() for throwing an error at a source position.

Retro: PR #559

Timeline. Dependabot opened a PR bumping js-yaml 4.1.0→5.4.1 (major) and antora 3.1.12→3.2.0 (minor) — first-order diff is one line in antora/package.json (antora minor bump); js-yaml is transitive-only via antora. The review agent ran on opus/high (2 iterations, $3.77) and APPROVED with Looks good to me, adding the ready-for-merge label. ~19 hours later, maintainer robnester-rh closed the PR without merging or commenting; Dependabot then posted its "I won't notify you again" message consistent with an @dependabot ignore this dependency intent.

Diagnosis. The agent's substantive analysis was actually sound (grep found no direct js-yaml usage; antora's engine constraint is met). The reason for closure is not a correctness gap — it is a repo-policy gap. This repo has renovate.json (extending github>conforma/.github//config/renovate/renovate.json) and no in-repo .github/dependabot.yml. Renovate is the sanctioned dep manager for this org; Dependabot PRs here arrive out-of-band (security alerts / defaults) and are routinely closed. The review agent has no signal for "this repo uses Renovate — Dependabot PRs should not be labeled ready-for-merge."

Two secondary infra findings from the trace:

1. The pr-risk-assessment sub-agent failed hard in iteration 2 because model claude-sonnet-4-5@20250929 is not enabled on the Vertex deployment. The fallback path is to omit the risk field and proceed to approve — a silent infra failure is being masked as "no risk."
2. Two iterations produced bitwise-identical agent-result.json; the second iteration re-derived the same verdict and burned tokens on the failed risk call.

Existing-issue check. Related open work that partially overlaps but does not cover the Renovate-vs-Dependabot policy angle: agents#448/#449/#616 (scope escalation for major lockfile bumps), fullsend#3015 & #3049 (breaking-change screening for Renovate PRs), agents#280 (LGTM-only bodies), agents#501 (suppress ready-for-merge on no-merge intent). None of these encode "detect dep-manager conflict at the repo level." The proposals below fill that specific gap and the risk-assessment silent-failure gap.

Proposals filed: 3 — see linked issues.

Proposals filed

• Add .github/dependabot.yml to disable Dependabot for the npm ecosystem (Renovate is the sanctioned dep manager) (in conforma/conforma.github.io)

Proposals skipped (target repo not allowed)

File manually or update create_issues.allow_targets in config.yaml:

• Review agent should detect dep-manager policy conflict (Renovate vs Dependabot) before approving bot PRs (fullsend-ai/agents)
• pr-risk-assessment sub-agent silent-fallback masks infra failure and defaults to approve (fullsend-ai/agents)
