docs: seed the wiki with everything the repository knows Thirteen pages in English, synthesized from docs/, the 34 odd/tasks records and the verified session memory: what PiCode is, getting it, the first-run wizard, architecture, the source build, the patch system, Pi inside, Gentle AI and ODD, distribution and licensing, CI and releases, the ADR index, roadmap and known state, and a glossary. Mirror of the repository's wiki/ folder.
