…lnate/once (CVE-2026-3449) Instead of pinning @tootallnate/once to a vulnerable v2.0.0, resolve http-proxy-agent to v7 which dropped the @tootallnate/once dependency entirely. This forces all consumers (codecov/teeny-request, jest/jsdom, lerna/make-fetch-happen) to use http-proxy-agent@7.0.0 which only depends on agent-base@7 and debug@4. This completely removes @tootallnate/once from the dependency tree, fully resolving CVE-2026-3449 without the ESM/CJS compatibility issues of @tootallnate/once@3.0.1.

Changes
"http-proxy-agent": "^7.0.0"Strategy
@tootallnate/once< 3.0.1 is vulnerable, but v3.0.1 is ESM-only (breaks CJS consumers with ERR_REQUIRE_ESM). Instead of pinning the vulnerable package, we resolved its parenthttp-proxy-agentto v7 which dropped the dependency entirely.Traced via
yarn why:codecov@3→teeny-request→http-proxy-agent@4→@tootallnate/once@1jest@27→jsdom→http-proxy-agent@4→@tootallnate/once@1lerna@5→make-fetch-happen→http-proxy-agent@5→@tootallnate/once@2All now resolve to http-proxy-agent@7.0.0 (no @tootallnate/once dependency).
