fix(deps): resolve js-yaml CVE-2026-84375

[asachs01]

Summary

Resolves the open HIGH Dependabot advisory GHSA-2883-xcg3-v3hh / CVE-2026-84375 for js-yaml (vulnerable range >= 4.0.0 < 4.3.2), clearing Vanta's High vulnerabilities test.

js-yaml is a dev-only transitive dependency pulled by cosmiconfig (via semantic-release). Applied a scoped npm override to force >= 4.3.2 (same pattern used in wyre-technology/afkbot):

"overrides": { "cosmiconfig": { "js-yaml": "^4.3.2" } }

Verification

• npm audit: 0 vulnerabilities (js-yaml advisory gone)
• js-yaml resolves to 4.3.2 in the lockfile
• npm run build, npm run lint, npm run typecheck, and npm test all pass

Supersedes Dependabot PR #89 (bare lockfile bump) — the scoped override is self-documenting and prevents regression on re-resolution.

Closes advisory #48.
