Show blog post publish date in search results

[cnunciato]

What

Adds the blog post publish date to blog results in the search dialog, as requested by folks searching the blog who wanted a date on each result.

Fixes #13801.

Flying a little bit blind here until the date field gets added to Algolia (which'll happen on release), but this should look like this once deployed:

How

Threads the date through all four layers of the search pipeline, scoped to blog hits only (docs/registry/etc. records are unchanged):

• layouts/index.json — Hugo's search-index JSON now emits a formatted date (Jan 2, 2006, matching the blog UI) for blog pages that have a non-zero date.
• scripts/search/page.js — carries date onto each Algolia record (undefined for non-blog records, keeping them clean).
• theme/src/ts/algolia/autocomplete.ts — renders the date under the description when a hit has one.
• theme/src/scss/_algolia.scss — styles it as small muted text. Uses literal Tailwind gray classes that the docs dark-mode block auto-remaps, so it reads correctly in both themes.

Notes

• The dates appear in the live dialog only after the Algolia index is regenerated, which happens in the normal build/deploy pipeline (Hugo produces public/index.json, then records are re-uploaded). Existing records won't have the field until then.
• date is a display-only attribute — deliberately not added to searchable attributes.
• Verified the theme webpack build compiles cleanly.

Tip

Summary: This is an infrastructure change (Hugo template + JS + SCSS + TypeScript) that surfaces a blog post's publish date on its Algolia search-result card. The four edits form one consistent chain: layouts/index.json computes a date string (formatted Jan 2, 2006) only for pages in the blog section with a non-zero date and adds it to the search index; scripts/search/page.js maps that field onto each hit (item.date || undefined); theme/src/ts/algolia/autocomplete.ts adds the optional date field to the hit interface and renders a .date element only when present; and theme/src/scss/_algolia.scss styles it. The wrongness that would matter here — dates leaking onto non-blog results, a mis-formatted date, or the render breaking when a date is absent — is guarded by the blog-section check, the IsZero guard, and the conditional render, so the guards line up end to end. Review passes: infra code review and a Hugo/link-integrity preflight (no findings). No factual claims were present to verify, and the change is not under content/blog/, so no editorial-balance pass applied.
