CB-WP-0028 T01/T02: the cards say what they do

ADR-0015 and the import. F18's fix: "I don't understand the GROUND card"
was never a design gap -- the card explains itself in the edition and we
never imported the explanation.

THE MEASUREMENT IS THE DECISION, and the gap is bigger than "one file of
nineteen". Of the file we DID vendor, the engine reads 5 of 13 columns:
title, problem_text, front_rules, reveal_effect and unresolved_effect were
discarded at parse time. The cheapest part of this pass costs no new bytes
and was sitting in the repo for eight days. And SCN_01 is hardcoded at
lib.rs:1824 -- the edition ships FOUR scenarios and the engine has never
dealt three of them. Nobody had said so.

ADR-0011's revisit condition is measurably absent, so the dependency
argument does not get re-run: across Actions, Solutions, Modes and
Scenarios there are ZERO doubled quotes and ZERO embedded newlines. The
hand reader's only job is comma-in-quoted-field, which it already did.
Refusing csv on a measurement rather than on a preference.

Vendored Actions, Solutions and Modes -- the text a player reads. Not the
production artifacts (BOM, Print_Manifest, Back_Designs, Symbols). NOT
Extensions.csv, which names content the designer placed outside the core;
importing it would break the claim that this engine plays the edition as
printed. It is now known to exist, which was the real risk.

One Table reader with four callers, because a per-file copy is how a
parser acquires four subtly different bugs. The GROUND card now shows
"Regulate. Restore the frame. Decide." with its GR/OU/ND text on demand;
Problems show their own titles where a priority number used to be.

The load-bearing test asserts the text is a SUBSTRING OF THE VENDORED
FILE rather than equal to a Rust literal -- a test comparing against a
hardcoded expectation would pass for a hand-copied string, which is the
drift this ends.

`edition` came out from behind #[cfg(feature = "scenarios")]. It was gated
because its only consumer was; the edition is the game's own data and the
shipped runtime now reads it. Test machinery and game content are
different things and only one of them is optional.

And edition-check was written for a single-file world: it compared the
first recorded digest against Problems.csv regardless of which file that
digest described. It now checks every file both ways -- a vendored file
with no digest fails, a digest naming an absent file fails -- and asserts
ADR-0015 D3's falsifier directly rather than trusting it.
