docs(8.0): RELEASES — native provider is @soulcraft/cor 3.0 (fix cortex 3.0 self-contradiction)

The 8.0 entry referenced a non-existent '@soulcraft/cortex 3.0' (line 447) while
the graph section already said '@soulcraft/cor 3.0' (line 44) — a self-contradiction.
The native provider was renamed cortex→cor; the 8.0 pairing is @soulcraft/cor 3.0
(the renamed successor to @soulcraft/cortex 2.x). Fixed the 8.0-section refs (the
Cor-compatibility block + the scale-path note); HISTORICAL 2.x refs in the v7.31.2 /
older entries are left intact (renaming them would falsify the changelog).

Cloud backup is now an operator concern: `db.persist()` produces a plain directory — sync it with `gsutil` / `aws s3 cp` / `rclone` / `azcopy`. Passing a removed storage type throws at construction with this exact guidance. |
 | Browser support | Node.js 22 LTS or Bun ≥ 1.0 (`engines` enforces `node: 22.x`); Deno works through its Node compatibility layer. |
 | `brain.migrateToDiskAnn()` / `brain.migrateToHnsw()` | Gone — there is one canonical `'vector'` provider slot. A registered native vector provider selects its own operating mode; there is nothing to call. |

The `mode: 'reader' \| 'writer'` multi-process roles are unchanged. |

 | `BrainyZeroConfig` type | Removed. 8.0 zero-config is automatic and internal — `new Brainy()` auto-detects storage, derives HNSW quality from `config.vector.recall`, picks `persistMode` from the adapter, and sizes caches to the detected container-memory limit. There is no config-generation type to import. |
 | `brain.isFullyInitialized()` / `brain.awaitBackgroundInit()` | `await brain.ready`. The built-in filesystem/memory adapters finish initialization synchronously inside `init()`, so a single readiness promise is the whole story — these methods were no-ops once cloud adapters were removed. |
