The only other cd left in the workflow mixed two working directories
in one step: docs/build-manual.py --site runs from the repo root, then
npm ci/astro build need docs/site. Split into two steps so each can
use working-directory instead, keeping the whole file cd-free and
consistent with the Cloudflare deploy step's fix.
Gitea/GitHub Actions auto-groups a multi-line run: script under
"Run <first line>". With `cd docs/site` as the first line, the
collapsed log tree showed that instead of the actual wrangler deploy
command. Moving the directory change to the step's working-directory
key drops cd from the script entirely, so the group label now reflects
the command that's actually running.
