chore(ci): adopt node-ci gold-standard reusable (#604)

Pilots the org **node-ci** gold-standard meta-reusable
(netresearch/.github#248). Replaces `lint.and.build.yml` + `codeql.yml`
+ `security.yml` with one `ci.yml` calling `node-ci.yml`
(lint/type-check/test/build + node-audit + codeql + gitleaks +
dependency-review). References the reusable's `@feat/node-gold-standard`
branch for validation; flips to `@main` once #248 merges. Required
checks (🔎 Lint, 🔨 Build) will be updated to the new `ci / …` names once
the run reports them.
