Follow-up to #3036 (merged), which fixed the bundle-step crash. With that unblocked, the unit job ran and surfaced 3 independent pre-existing breakages on DEV (all present on the pre-#3036 DEV baseline — not introduced by #3036). This PR fixes all three so the unit job goes green.

1. Hugo build broken — contains is not a Hugo function

hugo/layouts/shortcodes/tut-menu.html:21 used contains . "→". contains is not a Go-template/Hugo function; the operands are both strings, so this is a substring test → strings.Contains. The parse error failed the Hugo build (exit 1), cascading to 4 failures in hugo-homepage-partials.test.ts (homepage, /learn/, tutorial-navigator, featured-missions never built). Introduced by the new-file commit 8c2028daa.

2. srv-qa parsers.bundle — duplicate createRequire declaration

prebuild:parsers-bundle (package.json) injected a banner with the bare createRequire, colliding with esbuild-emitted import { createRequire } from 'node:module' carried in from scripts/parsers/directives/ui.ts + reference-links.ts → SyntaxError: Identifier 'createRequire' has already been declared (surfaced as an oxc vite:define transform error), failing 5 srv-qa test files at module load. Fix: use the aliased banner createRequire as __cjsBundleRequire — the exact convention scripts/bundle-shared.cjs already documents and uses for the sibling bundles.

3. Stale test assertions vs. the intentional callout/alert refactor

Commits 18e713de5 (CSS) and 71a8d70bc (render hook) deliberately moved alerts to <aside>/<details> rendered via the tut-alert.html partial, and broadened the CSS sibling rule to ~ :is(blockquote, aside, details). Three string-matching tests were left behind (source is correct):

• option-codeblock-indent-css.test.ts: ~ blockquote → ~ :is(blockquote, aside, details).
• option-tail-leak.test.ts: blockquote.alert-tip → aside.alert.alert-tip (the real rendered element).
• render-blockquote-hook.test.ts: assert the hook delegates to tut-alert.html passing .AlertType, and that the partial emits class="alert alert-{{ $type }}" — preserving the coverage intent against the new architecture.

Verification

• feat: add slug mapping endpoint and getEventProgress fallback #2 verified: regenerated parsers.bundle.mjs with the aliased banner → no duplicate top-level createRequire; node --check passes (valid ESM).
• feat: implement Admin UI (Fiori Elements + freestyle SAPUI5) #1 + feat: add CAP search service with HANA fuzzy search #3 string assertions verified against the real source files (grep-confirmed each expected substring exists).
• feat: implement Admin UI (Fiori Elements + freestyle SAPUI5) #1 + the pipeline tests (option-tail-leak, hugo-homepage-partials) rely on the Hugo build, which CI runs; confirmed locally that the contains→strings.Contains fix is the only blocker on the build path and the new aside.alert.alert-tip selector matches tut-alert.html's output for a non-collapsible tip.
