docs: admins keep a bypass on the branch rules
docs: the release lands its feed through a pull request now
docs: update the wiki to the source-build reality
The patch-system pages described the retired era (patches/, the
VSCodium archive, apply-picode.ps1). Architecture, Building, CI,
Distribution and Roadmap are rewritten from the canonical docs; the
Glossary, Getting PiCode and Home lose the stale references; The Patch
System becomes a tombstone. The agent layer is described as it is now:
native chat modified in the core over pi.
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.
