Cleanup de drift de convenciones: nakui-core era el unico crate del
monorepo que manteia version, edition y thiserror hardcoded, mientras
el resto heredaba del workspace y usaba thiserror v2. Eso significaba
que un bump global de version o edition se olvidaba sistematicamente
de nakui.

Cambios:
- [package]: version, edition, rust-version, license, authors, publish
  -> todos *.workspace = true. Agregado description (convencion).
- Deps compartidas migradas a { workspace = true }: serde, serde_json,
  thiserror (v1->v2), tokio, ulid, sha2.
- uuid migrado a { workspace = true, features = ["serde"] } — la feature
  serde no esta en el workspace dep porque nakui es el unico user;
  queda local opt-in en lugar de inflar el dep comun.
- Deps especificas de nakui (sin comparticion posible): rhai, petgraph,
  surrealdb permanecen inline con version local.

Verificacion: cargo build -p nakui-core verde tras el bump thiserror
v1->v2 — los 14+ enums de error de nakui no requirieron ajustes
(derive backwards-compat para patrones simples). cargo test -p
nakui-core --lib: 27/27 verdes.

Bonus en este commit: discovery.rs movio el import Ulid a #[cfg(test)]
porque el refactor a Card::new lo dejo unused en module-scope.

+### chore(nakui): alinear `nakui-core` con `[workspace.package]` y deps compartidas
+Cleanup de drift de convenciones: `nakui-core` era el único crate del
+monorepo que mantenía `version = "0.1.0"` / `edition = "2021"` /
+`thiserror = "1"` hardcoded, mientras el resto heredaba del workspace
+y usaba `thiserror = "2"`. Eso significaba que un bump global de versión
+o de edition se olvidaba sistemáticamente de nakui.
+
+Cambios:
+- `[package]`: `version`, `edition`, `rust-version`, `license`, `authors`,
+  `publish` → todos `*.workspace = true`. Agregado `description` (cumple
+  convención del resto de crates).
+- Deps compartidas migradas a `{ workspace = true }`: serde, serde_json,
+  thiserror (v1→v2), tokio, ulid, sha2.
+- `uuid` migrado a `{ workspace = true, features = ["serde"] }` — la
+  feature `serde` no está en el workspace dep porque nakui es el único
+  user; queda local opt-in en lugar de inflar el dep común.
+- Deps específicas de nakui (sin compartición posible): rhai, petgraph,
+  surrealdb permanecen inline con versión local.
+
+Verificación: `cargo build -p nakui-core` verde tras el bump de
+`thiserror` v1→v2 — el `#[derive(Error)]` de los 14+ enums de error
+en nakui no requirió ajustes (la API de derive es backwards-compatible
+para los patrones simples). `cargo test -p nakui-core --lib`: 27/27
+verdes, sin regresión.

 ### feat(card): `Card::new(label)` — alternativa segura a `Default::default()`
 Cierra la trap documentada de `Card::default()` que devuelve `id =
 Ulid::nil()`. Usar `Card::default()` "viva" colisionaba con cualquier
