docs(canon): name the last two callings — Reaver, Bloodsworn

All seven callings are now named; no [CANON-TBD] remains in the specs.

Reaver (Barbarian). To reave is to raid — occupational, like Sellsword and
Trapper, naming what he does for money rather than what he is inside. That is
the rule the five mock names already obeyed and that §8's own list broke: a
calling is what a village calls you, not what a rulebook calls you. Bearsark
and Wildman were rejected for naming a condition; Breaker for being generic.

Bloodsworn (Warlock) was not a new coinage — the cosmology minted it a day
after the races spec was written ("what the Margreave calls bloodsworn",
rule.blood-price), and the cosmology spec had already applied it. It is the
exact FTH-axis mirror of Bonesetter: one channels the Warden, one pacts a king
of the Seven. Accepted cost, recorded in the spec: alone among the callings it
names a condition rather than a trade — the villain who pacts Ghaul is
bloodsworn too. A second, occupational word (Cursewright, Hexman) was
considered and rejected as a distinction the player will never feel.

Also retires the stale "reconcile class names" note on M4 and records the two
contract migrations that milestone owes: the canon log's `race` field, and the
deserter origin's dead allowed_classes.

 *Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): calling blurbs + the Bloodsworn's patron choice (fixed); origins (variable). **~4 pieces.***
-- ○ **Character creation UI** — the mock's screen over our proven model: race + calling cards, six stats with **LCK hidden entirely** (§7), 3d6 floors, the **+3 additive-only spend-up** pool (§8, matches the `character-creation-stats` model), live origin blurb + nameplate. **Reconcile class names** here (§8 vs the mock's callings). Feeds new-game canon-log construction (already built). **⛨ saga:** `NewGame.construct` takes `creation` as a plain `Dictionary` — keep it that way. The creation *scene* produces that dict but must not become the only thing that can (a saga synthesizes it and skips the UI). Emit `race_id` + `calling_id` into it. *§2: state · depends on the creation model (M0) + Theme · goal: build a character.*
