Derive score-version fixtures from the SCORE_VERSION constant

Eight test and fixture files hardcoded scoreVersion: 2, a value the
constant has not held since v1.35.0. Now they import SCORE_VERSION and
use it, so a future bump cannot leave a fixture pinned to a stale
number.

The one genuinely historical case (record.test.ts, proving the input
fingerprint moves when the algorithm version moves) now derives both
its "previous" and "current" markers from SCORE_VERSION instead of two
unrelated literals, so the pair keeps its meaning after the next bump.
