release: 160.0.0 (#4050)

This is the release candidate for version `160.0.0`.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Mostly version/changelog packaging, but the release notes flag
breaking SnapController messenger and constructor requirements that
MetaMask clients must adopt when upgrading snaps-controllers.
> 
> **Overview**
> **Release candidate `160.0.0`** bumps the monorepo from `159.0.0` and
publishes **`@metamask/snaps-controllers@21.0.0`** (from `20.0.6`), with
the new **`[21.0.0]`** section and compare links in
`packages/snaps-controllers/CHANGELOG.md`.
> 
> The documented **breaking** changes in this cut move Snap lifecycle
and OTA update analytics into **`SnapController`** (messenger now needs
`AnalyticsController:trackEvent` plus install/update/uninstall events,
and the constructor needs **`clientConfig`** for OTA analytics).
**`SnapRegistryController`** gains **`requestPeriodicUpdate`**, along
with dependency bumps for `@metamask/storage-service` and
`@metamask/approval-controller`.
