fix(docs): address review on the Anchors and Training Data article

[raifdmueller]

Follow-up to #586, addressing the CodeRabbit + Copilot review.

• main.js (real bug, CodeRabbit): handleLanguageChange() had no case for /training-data-vs-practice, so toggling EN/DE on the article did not re-render it, unlike every other doc route. Added the branch (mirrors harness-inventory).
• router.js (Copilot): aligned the browser/tab title with the article's actual title (An Anchor Delivers Only as Far as the Prior Reaches) instead of the nav label.
• article (Copilot): dropped the "full fully-dressed" wording redundancy (2 spots).

Skipped the "&" → "and" nav-label nit — "&" is idiomatic and short in a nav menu.

The cross-model validation (GPT-5 / Gemini) from @JensGrote's review is intentionally not in this PR — he is opening a separate PR for that with his raw data.

Walkthrough

Die PR ergänzt sprachliche Verbesserungen der Seite training-data-vs-practice.adoc und verdrahtet ihre Route mit neuem Titel in der Website-Infrastruktur. Die Dokumentation wird stilistisch überarbeitet, während main.js und router.js die Route und deren Anzeige registrieren.

Changes

Training-Data-vs-Practice Seite

Layer / Datei(en)	Zusammenfassung
Dokumentinhalts-Überarbeitung docs/training-data-vs-practice.adoc	Im einleitenden NOTE wird „full fully-dressed" zu „complete fully-dressed" korrigiert. Im Anchor-Diskussionsabschnitt werden attributionsbezogene Sätze sprachlich präzisiert und die Ceremony-Formulierung gestrafft, ohne Referenzen zu entfernen.
Route-Verdrahtung und Titeleintrag website/src/main.js, website/src/utils/router.js	Die Route /training-data-vs-practice wird in handleLanguageChange() hinzugefügt, um Dokumentinhalte zu laden. Der Titelstring in ROUTE_TITLES wird von „Anchors and Training Data — Semantic Anchors" auf „An Anchor Delivers Only as Far as the Prior Reaches — Semantic Anchors" aktualisiert.
