ci(codeowners): add aaltshuler to engineering role (#147)

Restores aaltshuler as an `engineering` code-owner (removed in #142), so
`crates/**` and repo-infra PRs have a second reviewer besides the sole
owner ragnorc — unblocking review of author-ragnorc PRs (e.g. #132) that
ragnorc cannot self-approve.

Edited the source of truth (.github/codeowners-roles.yml) and re-rendered
.github/CODEOWNERS + the docs/dev/codeowners.md tables via
.github/scripts/render-codeowners.py, per the documented flow.
