mesorah: a Torah reference inside a mesorah citation is the citation's address

Live, "Rashi on Devarim 6:5 indicates <a claim Rashi does not make>" came
back tov: "Devarim 6:5" inside the citation was read as a Torah citation,
which anchors the claim in Torah by reference (tablet 49's rule). The
claim is about Rashi and must rest on Rashi — the mesorah passage is a
given source — or on nothing. Mesorah citations are now blanked before
the Torah readings (references and the Torah anchor); an output's own
"Devarim 6:5" still anchors in Torah. korban 295/1 skipped.
