fix(creation-content): four fragments were reading the blurb back to the player

The creation screen shows a race's blurb on its card and the chosen calling's
blurb in the detail panel directly above the DM panel. Blurb and fragment are on
screen at the same moment, inches apart — so a fragment that paraphrases its own
blurb makes the DM sound like it is reciting the card. Four did:

- bonesetter lifted two clauses verbatim ("you set the bone, you say the words")
- reaver re-ran the blurb's door image with the same sentence shape
- hedge_mage re-opened on "what you know" and re-landed the dead teacher
- beastfolk repeated both the claws and the being-judged beat

Each now says the NEXT thing instead: the hour they wake you and which of the
two trades you will not claim credit for; the employer who arranges to be
elsewhere; where you went to fail safely and what the book's gaps cost your
skin; the town that takes your coin and still wants you outside the walls.

beastfolk's rewrite also breaks the race-set monotony — it no longer opens "You
were born" (now unique to human) and drops the shared "X, and you have…" spine,
so clicking the four cards in a row stops reading as one voice.

The parity test guarded presence but could not fail on the three properties that
actually make all 28 race×calling concatenations grammatical. It now asserts
race fragments start uppercase and end with '.', and calling fragments start
lowercase and end with '.' — verified by breaking both and watching all four new
assertions fire.
