wiki-kb/install.sh
kuhyx 71e4a6115e Consolidate CK3/KCD wiki knowledge bases into one generic wiki-kb
Merges ~/ck3-knowledge and ~/kcd-knowledge, which were 90% duplicate code and
neither of which had ever been committed anywhere.

Works on any wiki, not just MediaWiki:
- sources.py splits the engine-specific parts (enumerate, fetch) behind a Source
  protocol. MediaWikiSource is preferred whenever an api.php exists;
  SitemapHtmlSource handles custom engines with no API (verified on Fextralife).
  Everything downstream was already source-agnostic.
- scripts/detect_wiki.py probes /api.php, /w/api.php then /sitemap.xml and prints
  the config to use. The API path and article URL vary independently — Fandom
  serves /api.php but /wiki/{Title}.
- Profiles are plain env files, since config.py was already fully env-driven.

Per-wiki behaviour that must be measured rather than assumed:
- Subpage policy. On the CK3 wiki "A/B" is a mod; on the KCD wiki it is the
  sequel, and rejecting subpages deletes 441 pages of wanted content.
- Noise sections. "Other languages" tables were 7% of KCD chunks and matched
  English queries by repeating every title in eight languages.
- Variant tagging for wikis covering two editions, with scopes that exclude the
  other edition but keep both/unknown pages.

Build performance: length bucketing in embed_efficiently is 2.7x (fastembed pads
each batch to its longest member; 184-char median vs 2000-char max). With noise
sections that is 61 min -> 20 min on a 6,140-page wiki at half the workers.

Fandom portable-infoboxes are transformed to tables before markdownify —
otherwise stat values survive but detach from their labels.

100% branch coverage, ruff clean.
