Nubenetes Bot 19b7b44e20 feat(v2): restore in-page search/tag filter & drop redundant Markdown TOC 
Fix: the per-page resource search box with maturity tag-pills stopped
appearing after navigation.instant was enabled (DOMContentLoaded fires only
on first SPA load). Reworked v2_filter.js to init via Material's document$
observable with a DOMContentLoaded fallback, guard double-injection, bind the
clickable-tag delegation once, and add a no-results state. Cache-bust ?v=2.9.12.

Change: removed the duplicated Markdown "## Table of Contents" from all 156 V2
content pages and from v2_optimizer.py — it forced hundreds of links of scroll
on large pages. Replaced by Material's native sticky "On this page" TOC
(removed toc.integrate, added toc.follow). tags.md keeps its TOC (it is an index).
