v0.2.0-pre.9

Pre-release on `@next`. Snapshots auto-cadence + S3 bundle adapter + storage capability matrix.

Highlights

• Snapshots auto-cadence — `withSnapshots({ snapshotPolicy: { mode: 'debounce'|'interval' } })`. Automatic whole-vault snapshots to a single rolling `__auto` key, retention-exempt so the timer never evicts labeled checkpoints. Default `manual` (no behavior change). (#272)
• `s3Bundle()` (`@noy-db/to-aws-s3`) — a `NoydbBundleStore` over S3 (OCC via `IfMatch`/ETag → `BundleVersionConflictError`); verified against real S3.
• Storage capability matrix — every `to-*` adapter now declares `capabilities: { record, vault }` (schema-enforced); generated docs table with a CI drift guard.

Install

```
pnpm add @noy-db/hub@next @noy-db/to-aws-s3@next
```

`latest` stays `0.1.0-pre.4`. Closes #272.
