fill the three empty pages: Installing-Tycho, FAQ, Contributing Installing-Tycho: prerequisites, clone+make, hello, the optional extras, the platform notes, and how to verify a build with the local gate. FAQ: the four questions from the README plus the production-readiness answer Home anchors to. Contributing: condensed from CONTRIBUTING.md -- bug reporting, the local-only gate, the two surprising rules, code style, submission.
Mirror the reader docs into the wiki (tutorial, thesis, architecture, from-c-to-arenas, reference/, guides/); links rewritten to wiki pages, spec/internals kept as repo links
Populate wiki: orientation hub (Home, install, FAQ, documentation map, contributing) linking to canonical /docs
