Add a Releases section with a landing index and the Release 11 (Metis) release notes, covering the platform features (branching, checkpointing, custom filesystems and persistent volumes, custom network configuration, network shield and relay, and the plugin API) and the supporting tooling. Wire the Releases category and the /releases redirect into the Zudoku navigation. Signed-off-by: Jerome Jaggi <jerome@unikraft.io>

| Release 11 is a major step forward for the platform, and it comes jam-packed. Headlining it are advanced snapshotting capabilities — branching and checkpointing — alongside custom filesystems for persistent storage, and a plugin API that transparently extends a microVM with your own code. A sandbox plugin built on it is already available to enterprise customers. | ||
|
|
||
| Also on the sandbox track — but useful for all use cases — is our new network shield. It sits between any microVM and the public Internet, filtering traffic and injecting tokens, credentials or secrets so they never have to live inside the microVM (read: agent) itself. The shield is implemented as a minimalist, scale-to-zero microVM of its own, so it is as strongly isolated as everything else you run — and, being a microVM, extremely flexible in what it can do (iptables, eBPF, and so on). |

| **Why it matters:** Branching is the foundation for stateful instance workflows on the platform. | ||
| It enables fast, low-downtime cloning of live workloads for testing, scaling, and recovery. | ||
| It applies to many use cases, including launching sub-agents or branching large production databases to safely develop on them. |

[Microsoft.Adverbs] Remove 'safely' if it's not important to the meaning of the statement.

|
||
| **Requirements and limitations:** Requires a valid license. | ||
| Checkpointing only works with block-based volumes (for example, `ext4`). | ||
| You load checkpoints by creating a new instance from them; in-place rewind of an instance to a previous checkpoint isn't part of this release. |

| ### Custom network configuration | ||
|
|
||
| You can now create microVMs with several network interfaces and fully custom network configuration via `POST /v1/instances`: |

[write-good.Weasel] 'several' is a weasel word!
| ``` | ||
|
|
||
| The first interface is the **primary interface**: the `private_ip` that the instance returns always comes from it, and the proxy forwards traffic to the primary interface's IP. | ||
| If you omit `ip` and `tap_name`, the platform chooses a TAP device from its pool; you must specify both fields or neither. |

[Microsoft.Terms] Prefer 'personal digital assistant' over 'agent'.
| #### Image pruning | ||
|
|
||
| The agent now automatically prunes unused images from disk. | ||
| When no running or stopped instance references an image any longer, the agent garbage-collects it to reclaim space; if you need the image again later, the agent pulls it on demand from the registry. |

| You can now check real-time metrics for all your resources and inspect instance logs. | ||
| You can start and stop instances directly from the UI and manage your organization, including user management. | ||
|
|
||
| Coming soon, you'll also be able to SSH directly into a particular instance, create and delete instances, and inspect the lifetime of an instance as you checkpoint or fork it. |
