Group 1 of the sweep listed cmd/mavend/ordinal.go, and it was still
picking a position by stem prefix: {"перв", 1}, {"втор", 2}. The lexicon
already carries every form with its position and "последний" as -1, up to
twelve rather than five, so parseOrdinal reads that instead. "вторым" and
"седьмую" were missed before and now land.
A wider set opens one hole the stems did not have. Russian names a half
hour with the genitive ordinal of the hour it is entering, so "в половине
восьмого" would read as the eighth thing she read out. The forms of
"половина" move into the lexicon as half_hour, where the clock rewrite in
internal/router/halfpast.go and this refusal read one copy, and
parseOrdinal skips an ordinal standing behind one.
Six new parseOrdinal cases. cmd/mavend, internal/router, internal/lexicon
and internal/calendar all pass.
