docs: link same-wiki pages by name instead of by full GitHub URL
Every same-wiki link was written as a full github.com URL. On GitHub the two
forms are identical -- it resolves a bare page name against the wiki it is
rendering -- but this wiki also ships inside the Convert Claude plugin as a
read-only mirror, and there they are not identical at all: a skill routes an
absolute URL to "external", so the page sitting on disk beside it never gets
opened, and the answer is reconstructed instead of read. This repo is private,
so the fetch that would rescue it returns 404.
Cross-wiki links keep their absolute form -- a bare name would resolve inside
this wiki and land on the wrong page. _Sidebar.md and _Footer.md are untouched:
GitHub nav chrome, absolute by convention, on no skill routing path. Anchors are
preserved.

docs: bootstrap Convert Ruby SDK wiki
Shared cross-SDK concept docs (copied from the sibling wiki, links rewritten to
this wiki) + Ruby-specific pages (Quickstart, Installation, Initialization,
Configuration, ReturnTypes & Sentinels, CodeExamples, ForkSafety & Runtime
Recipes, TrackingControl, Testing, Changelog) + AI_Index routing table, Home,
sidebar/footer, CLAUDE authoring rules, and sdk-docs-config readme.io mapping.
