feat(political-intelligence): localise all 14 pages, link every artifact, enrich SEO

[Copilot]

The 14 political-intelligence*.html pages linked only to stream folders on GitHub (not individual artifacts), rendered methodology/template/stream descriptions in English regardless of target language, and carried a minimal SEO header.

Artifact-level links

• New DailyArtifact + collectStreamArtifacts() walks each analysis/daily/$DATE/$STREAM/ recursively.
• renderDailyDay() emits an accessible <details> per stream (collapsed, localised summary + count) listing every .md/.json as <icon> <localised title> <filename-pill> linking to its GitHub blob URL.
• .pi-stream a → .pi-stream-link so artifact links don't inherit the stream-button styling; new .pi-stream-artifacts* / .pi-artifact* styles.

Full per-language localisation (EN, SV, DA, NB, FI, DE, FR, ES, NL, AR, HE, JA, KO, ZH)

• New i18n records: STREAM_NAME_I18N, STREAM_DESC_I18N, STREAM_GENERIC_DESC_I18N, METHODOLOGY_DESC_I18N, TEMPLATE_DESC_I18N, TEMPLATE_GENERIC_DESC_I18N, ARTIFACT_TITLE_I18N, LIBRARY_NAME_I18N.
• CatalogEntry now carries library: 'methodologies' | 'templates'; localisedCatalogDescription(file, lang, library, fallback) resolves at render time with a localised generic fallback so unknown filenames never leak English.
• renderCatalogGrid() / renderDailyDay() take lang and use artifactTitle(file, lang) + streamDisplayName(name, lang) + streamDescription(name, lang).

SEO

• Head: preconnect/dns-prefetch to github.com + hack23.com, <link rel="sitemap">, per-language RSS <link rel="alternate">, news_keywords, generator, publisher, referrer, Content-Language, og:locale:alternate × 13, og:updated_time, article:publisher|section|modified_time|published_time, article:tag × N, twitter:creator, twitter:image:alt.
• JSON-LD: CollectionPage gains mainEntityOfPage, dateModified (latest daily), publisher logo, richer about[], and hasPart[].description; new third ItemList graph enumerates the 14 most recent days for richer SERP snippets.
