ci(codeowners): aaltshuler owns all paths; remove ragnorc (#169)

Engineering and docs roles both resolve to @aaltshuler; every path
(catch-all, crates/**, docs/**, repo-level docs) now requires their review.
CODEOWNERS and the doc tables regenerated from codeowners-roles.yml via
render-codeowners.py.
