chore: bump js-yaml and eslint in /plugin

[dependabot]

Bumps js-yaml to 4.3.0 and updates ancestor dependency eslint. These dependencies need to be updated together.

Updates js-yaml from 4.1.1 to 4.3.0

Changelog

Sourced from js-yaml's changelog.

4.3.0 - 2026-06-27

Added

• [backport] Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.

Fixed

• Restore umd builds back to es5.

Removed

• [backport] maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

[4.2.0] - 2026-06-01

Added

• Added docs/safety.md with notes about processing untrusted YAML.
• Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.
• Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.
• Added sourcemaps to dist/ builds.

Changed

• Stop resolving numbers with underscores as numeric scalars, #627.
• Switched dev toolchains to Vite / neostandard.
• Updated demo.
• Reorganized tests.
• dist/ files are no longer kept in the repository.

Fixed

• Fix parsing of properties on the first implicit block mapping key, #62.
• Fix trailing whitespace handling when folding flow scalar lines, #307.
• Reject top-level block scalars without content indentation, #280.
• Ensure numbers survive round-trip, #737.
• Fix test coverage for issue #221.
• Fix flow scalar trailing whitespace folding, #307.
• Fix digits in YAML named tag handles.

Security

• Fix potential DoS via quadratic complexity in merge - deduplicate repeated elements (makes sense for malformed files > 10K).

[3.14.2] - 2025-11-15

• Backported v4.1.1 fix to v3

PR Summary

Medium Risk
Major ESLint upgrade only affects lint/CI, but it can break builds on older Node versions or with legacy eslint-config-standard plugins; js-yaml bump is transitive with minor parsing/safety behavior changes.

Overview
Updates dev-only dependencies under plugin/ via Dependabot: eslint is raised to ^10.6.0 (with the lockfile resolving 10.6.0), and the transitive js-yaml used by ESLint’s config stack is resolved to 4.3.0.

Changes are limited to plugin/package.json and plugin/package-lock.json—no plugin runtime (www/, src/) code is modified. npm run eslint still invokes the local node_modules/eslint binary; expect a stricter toolchain and ESLint 10’s Node engine requirement (^20.19 / ^22.13 / ≥24) to affect CI or local lint runs if the environment is older.
