docs: fix AI_Index canonical-source path, add CLAUDE.md for shared-docs guard rails AI_Index.md previously described the shared-docs canonical source as "../backend.wiki/" and linked to a fabricated github.com URL. Corrected to name the real canonical path within the backend repo and describe (not link) the private source. Added CLAUDE.md at the wiki root documenting: (a) the shared vs PHP-specific page split and decision rule before editing, and (b) the writing rules for shared docs — never reference the private backend wiki or its filesystem paths, never invent URLs, prefer package + class + method references over file:line.
