The override "elliptic": ">=6.6.1" was added in PR #26 to address
GHSA-848j-6mx2-7j84 (CVE-2025-14505), but it is a no-op because
elliptic@6.6.1 IS the vulnerable version and no patched version exists.
No upstream fix is available — elliptic@6.6.1 is the latest release.
CTO decision: remove the no-op override, accept residual build-time risk.
Dependency is build-time only and not shipped to production.
