AGENT.md now points at .ai/guidelines, so the guidelines move into the
repository and the reference resolves on a fresh clone. Completes the
exported doc comments in the console manifest and registry left from
the lint pass, and ignores local scratch files (.DS_Store, sdkscratch).
The root Barkfile's include files (Barkfile.campbellwireless,
Barkfile.ruckstack) stay local on purpose: they are personal
infrastructure and Barkfile.campbellwireless currently does not parse
(a treatvault block inside a project block, which the parser rejects).
