Pull request overview

This PR aims to eliminate npm audit findings by upgrading several direct dependencies, adding npm overrides to force patched transitive versions, and introducing an allowScripts allowlist for install-script transparency.

Changes:

• Upgrade direct dependencies (notably @azure/arm-resourcegraph, containerization-assist-mcp, js-yaml) and refresh root lockfile accordingly.
• Add npm overrides to force patched transitive versions (e.g., diff, serialize-javascript, js-yaml under dockerfilelint).
• Add allowScripts entries in both the root and webview-ui packages; normalize the webview lockfile metadata.

✅ Addressed All Copilot Review Comments

Thank you @copilot for the thorough review! I've addressed all 4 comments in commit 93a68f0:

1. ⚠️ js-yaml ESM/CommonJS Incompatibility (High Priority)

Comment: js-yaml@5 is ESM-only but this project compiles to CommonJS (tsconfig.json sets module: "CommonJS"), causing ERR_REQUIRE_ESM at runtime.

Resolution: ✅ Downgraded both direct dependency and override:

• Direct: js-yaml from ^5.0.0 → ^4.2.0
• Override: dockerfilelint.js-yaml from ^5.0.0 → ^4.2.0

Security Status: js-yaml@4.2.0 already includes fixes for both advisories (GHSA-h67p-54hq-rp68, GHSA-mh29-5h37-fv8m), so security remains intact with 0 vulnerabilities.

---

2. 🔧 Mocha Overrides Using Minimum Patched Versions (Medium Priority)

Comment: Using diff@^9.0.0 and serialize-javascript@^7.0.6 forces versions outside Mocha's declared ranges. Use minimum patched versions to reduce breaking-change surface.

Resolution: ✅ Updated to minimum patched versions:

• diff: ^9.0.0 → ^8.0.3 (minimum version with GHSA-73rr-hh4g-fpgx fix)
• serialize-javascript: ^7.0.6 → ^7.0.5 (minimum version with security fixes)

---

3. 🧹 Remove Unused allowScripts Entry (Medium Priority)

Comment: fsevents@2.1.3 does not appear in the root package-lock.json dependency graph.

Resolution: ✅ Removed fsevents@2.1.3 from allowScripts in root package.json

Note: fsevents@2.3.3 is still correctly whitelisted in webview-ui/package.json where it is actually used.
