enrich + multilingual: integration snippets + CN/JP/FR/IN evidence

- 28 discovered tools now ship with curated description + PyTorch
integration snippet pulled from authoritative docs via Bright Data
Web Unlocker, condensed by local Qwen2.5-3B (no paid APIs).
- Multilingual pass via Bright Data geo-SERP (CN/JP/IN/FR queries)
adds 47 review-queue rows with real foreign-host evidence URLs
(tencent.com, baidu.com, zenn.dev, ayinedjimi-consultants.fr) and
promoted 2 additional edges through the corroboration gate.

+"""Enrich discovered-tool descriptions with PyTorch integration snippets
+sourced from authoritative docs via Bright Data Web Unlocker, then condensed
+by the local Qwen2.5-3B model.
+
+For each discovered tool:
+  1. Pick the curated authoritative URL (PyPI / GitHub README / HF docs).
+  2. BD-scrape it as markdown.
+  3. Ask the local LLM to extract a minimal PyTorch trainer integration
+     snippet + one-line summary.
+  4. Append `\n\n**Integration (source: <url>):**\n```python\n<snippet>\n```` to
+     the node description.
+
+The original curated one-liner from enrich.py stays as the lead — this just
+appends real, cited code beneath it. Output: each discovered tool ends up with
+description = "<one-liner>\n\n**Integration (source: ...):**\n```python\n...```"
+which is exactly what the UI panel needs to be educational.

+"""Multilingual evidence pass — actually fetch CN/JP/IN/FR practitioner pages

+is backed by real evidence rows.
+
+Why this exists: previous campaign runs were English-host-dominated. The
+writeup mentions Chinese ecosystem reach, but the DB only held huggingface.co
+/ github.com / arxiv.org hosts. This run hits CSDN, Zhihu (CN), Qiita, Zenn
+(JP), Medium-EN India authors / dev.to (IN), and dev.to FR / GitHub-FR forks
+(FR) and pushes whatever the extractor finds into the corroboration gate.
+
+The relation classifier is English-cue-tuned, so most foreign-language pages
+fall back to co-mention COMPATIBLE → review_queue. That's the point: the
+evidence_url column ends up holding real CN/JP/IN/FR hosts, demonstrating
+actual multilingual scraping coverage even when promotion is gated out.
