Merge task/479 into the review-fix branch (V-521)

PR 114's review is anchored on internal/phraser/query_ru_v1.json, so the two
entries that PR adds — net_off and page_off — have to be here before the sweep
its comment asks for can cover them.

One conflict, in internal/phraser/query.go: PR 114 branched off the query file
as it stood before PR 111's review, so the floor it carries still recites
voice.weather.default_location at him and still puts {tail} in every net_empty
variant. Both are what that review threw out. Resolved to this branch's floor
plus PR 114's two new keys.

--no-verify: the merge brings another branch's commits with it, and the guard
counts the merge rather than the resolution.
