fix(deps): resolve 6 Snyk vulnerabilities via npm overrides (+Claude)

[dhruv-parekh-cs]

Automated Snyk remediation pass (/snyk-fix, run date 12-Aug-2026). Surface in scope: Node.js. Public repo — Conventional Commits used.

Summary

All six findings are transitive (nothing vulnerable is declared directly), so each is pinned through the existing overrides block. Caret ranges throughout, so future compatible patches aren't blocked.

Why brace-expansion is path-scoped rather than a single top-level override

The tree holds two brace-expansion majors at once — 2.1.2 under minimatch@5 and 5.0.7 under minimatch@10 — needing ≥2.1.4 and ≥5.0.9 respectively. A single top-level "brace-expansion": "^5.0.9" would force minimatch@5's copy across a major boundary. The two path-scoped entries patch each in place instead, matching the "minimatch@3": { … } selector style already used elsewhere in this repo's overrides.

Application-code changes

None. package.json / package-lock.json plus one .talismanrc line — see below.

.talismanrc change (please review)

The Talisman pre-commit hook already allowlists package-lock.json by content checksum. The lockfile content changed, so its recorded checksum went stale and blocked the commit (Talisman flags npm integrity fields — base64 SHA-512 digests — as "base64 encoded texts"). Only that one checksum was updated to the value Talisman itself reported; no new file was allowlisted and no scan was bypassed.

Validation

• npm install — pass, no peer-dependency warnings
• npm test — pass
• npm run build — pass
• snyk test --all-projects re-scan — clean, 0 issues remaining (the repo's own pre-commit Snyk gate also reported "Tested 463 dependencies for known issues, no vulnerable paths found")

Needs human review

None for this repo.

Pull request overview

Updates dependency resolution to remediate six transitive Snyk findings in this Node.js CLI repo by adding/adjusting npmoverrides, regenerating the lockfile accordingly, and updating the Talisman allowlist checksum for the modified lockfile.

Changes:

• Added overrides entries to force patched versions of fast-uri, js-yaml, and brace-expansion (scoped by minimatch major).
• Updated package-lock.json to reflect the new override-driven dependency graph.
• Updated .talismanrc checksum for package-lock.json so pre-commit secret scanning does not block the changed lockfile.
