* Introduces the `emptydir_mode` config flag to allow instructing the runtime
to create a block device for emptyDir volumes.
* The block device is created in the original emptyDir folder on the host
so that Kubelet can monitors its disk usage and evict the pod if it exceeds
its sizeLimit. This matches runc and virtio-fs.
* The block device's disk image file is sparse to minimize host disk
footprint.

Virtio-mmio transport is not hardened for confidential computing (unlike
virtio-pci). Reject config that would use virtio-blk-mmio for rootfs/block
when confidential_guest is set, so CoCo guests only use virtio-blk-pci.

This commit introduces three new fields to the `SecurityInfo` struct
to support SEV-SNP (Secure Nested Paging) attestation and measurement
capabilities:
(1) `snp_id_block`: A 96-byte Base64-encoded ID block for the
SNP_LAUNCH_FINISH command.
(2) `snp_id_auth`: A 4096-byte Base64-encoded authentication structure
accompanying the ID block.
(3) `snp_guest_policy`: A bitmask for the SNP guest policy, passed to
the SNP_LAUNCH_START command.
These fields enable users to provide identity information to the SNP
firmware, allowing for remote attestation and verified guest launches.

Memory::new()
(2) Initialize/adjust memory values via kata-types MemoryInfo (single

(3) Replace sysinfo::System::new_with_specifics with

The runtime-rs shim was failing to load its configuration when deployed
via kata-deploy because it couldn't correctly parse the ConfigPath passed
by containerd. The previous implementation naively skipped the first 2
bytes of the options and interpreted the rest as a UTF-8 string, which
doesn't work since containerd passes a properly serialized protobuf
message of type runtimeoptions.v1.Options.
This change adds the runtimeoptions.proto definition to the protocols
crate and updates the load_config function to correctly deserialize the
protobuf message and extract the config_path field, matching how the Go
runtime handles this via typeurl.UnmarshalAny.

line appropriately, based on the indicated initramfs or kernelinit

This commit introduces the capability to dynamically configure
`queue_size` and `num_queues` parameters via Pod annotations.
Currently, `kata-runtime` allows for static configuration of
`queue_size` and `num_queues` for block devices through its config
file. However, a critical issue arises when a Pod is allocated fewer
CPU cores than the statically configured `num_queues` value. In such
scenarios, the Pod fails to start, leading to operational instability
and limiting flexibility in resource allocation.
To address this, this feature enables users to override the default
queue_size and num_queues parameters by specifying them in Pod
annotations.This allows for fine-grained control and dynamic adjustment
of these parameters based on the specific resource allocation of a Pod.

Refactors `LinuxContainerCpuResources` and `LinuxSandboxCpuResources`
to track calculated vCPU allocation using `f64` (fractional float)
instead of `u64` (milliseconds).
This ensures more precise resource calculation (`quota / period`) and
aggregation by avoiding rounding errors inherent in millisecond-based
integer tracking.

We need to ensure that we do not blindly append nor blindly override the
kernel parameters set by default, but rather modify the values in case
they exist, and append in case they do not.
Now we're actually making golang and rust runtime behave the same, as so
far they were behaving differently, each version wrong in its own way.

The update removes the deprecated adler crate from our dependencies. In

This commit introduces the configuration flag `disable_guest_empty_dir`
to control the placement of Kubernetes emptyDir volumes.
By default, the value is set to `false`, maintaining the current
behavior of creating emptyDirs within the guest VM
When set to `true`, emptyDirs will be created on the host filesystem.
This is essential for scenarios where users need to share data between
the host and the guest VM via an emptyDir.

Separated the checks for tmpfs and disk-based emptyDirs from an
`if-else if` block into two distinct `if` statements. This clarifies
the logic by treating each volume type detection as an independent task.
Additionally, updated the type for disk-based emptyDirs to the more
semantically accurate `KATA_K8S_LOCAL_STORAGE_TYPE`. This allows for
more specific handling downstream, distinguishing them from generic
host path mounts.
