v1.13.0

## Engram Cloud lands in stable

This release brings the cloud-enabled Engram work into `main`: hosted sync, the cloud dashboard, autosync restoration, project controls, audit visibility, and the Obsidian Brain beta path are now part of the stable line.

## Highlights

- Added the integrated Engram Cloud runtime and dashboard.
- Restored cloud autosync push/pull flows for local-first memory replication.
- Added project-scoped cloud controls, allowed-project enforcement, and sync pause behavior.
- Added audit-log visibility for rejected paused-project sync attempts.
- Improved dashboard UI, diagrams, and Engram Cloud documentation.
- Included the Obsidian Brain beta exporter/plugin scaffold so memory graphs can be explored from Obsidian.

## Upgrade

```bash
brew upgrade engram
```

## Notes

- Engram Cloud server deployments still require explicit runtime configuration.
- Obsidian Brain remains beta/documented separately while the core release stabilizes.
- Homebrew artifacts are generated automatically by GoReleaser.
