v0.7.9.2 — two things the table could hear that only one seat should

Both leaks were found while planning the common board (Gitea#20 step 1),
and both are live multiplayer bugs with or without that display, so they
are fixed now rather than with 0.8.0.

`game.log` is one shared list and `linesSince(seat)` slices it with no
per-seat filter, so every line reaches every player. It carried the SEED
in the opening line of each multiplayer game — the whole future of the
deal — and the NAME OF A CARD DRAWN BLIND from the face-down Home Office
deck. Solitaire deliberately keeps both: a one-seat table has nobody to
leak to, the seed is what a bug report quotes, and a player's own history
naming their own draw is the record. A Department slot is face up and
stays named. The drawer still learns their card through `justDrawn`,
which already goes to that seat alone.

Neither was found by a test. Every test in `redaction.test.ts` passes an
empty log, so the whole of narration has sat outside the redaction net
since the net was built. Both now have tests there; TODO #91 carries what
is still owed and supersedes #78, which described a gap that had already
been closed and never mentioned this one.

`docs/rules/` had no current description of the game, and `content.ts`
named `card-reference.md` as the file that carries what the cards say —
a file whose own banner says not to use its numbers, describing the
v0.4.5 deck where 3/4 is a Mail-Express with three coaches. Every file in
that directory is a deliberate historical record, so none of them is
rewritten. `as-built.md` is new and GENERATED from the same catalogues
the engine instantiates from, with a test that re-runs the generator and
fails when the checked-in file disagrees. A hand-written replacement
would have drifted the same way, for the same reason.

TODO.md: #32 closed — the playtest migration note did its job and the
jump is made; the durable fact it carried is kept. #78 retired in favour
of #91. The "play it at a table" section now records that 0.7.4-0.7.9
were test-run without change requests, and that more testing comes at the
end of the 0.7.9 series.

897 tests pass, up from 891.

+/**
+ * The card reference must not drift from the cards.
+ *
+ * `docs/rules/card-reference.md` spent several releases describing the v0.4.5 deck — twelve numbered
+ * trains, "3 / 4 Mail-Express, 3 coaches" — while `content.ts` had train 3 as the Express with two
+ * freight cars and a per-location freight rule. Worse, `content.ts` named that file as "the place
+ * that now carries what the cards say", so the code sent readers to a table its own banner told them
+ * not to trust. Nothing failed, because nothing checked.
+ *
+ * `docs/rules/as-built.md` is emitted from the same exported catalogues the engine instantiates
+ * from, and this re-runs the generator and compares. Change a card face without regenerating and
+ * this goes red — which is the whole point: a document nothing verifies is a document that will be
+ * wrong, and this project's own history is the evidence.
