Hyperlight prerelease changes snapshot compatibility and MSR handling

The latest prerelease of hyperlight-dev/hyperlight introduces several breaking changes, as detailed in the project's GitHub release notes. Guest MSR state is now saved and restored across snapshots, with SandboxConfiguration::guest_msrs specifying which MSRs are captured and restored. On KVM, only declared MSRs can be accessed by the guest, while this restriction is not enforced on MSHV and WHP. Additionally, filesystem paths are now represented using PathBuf instead of String, requiring callers to convert String inputs using .into(). Fixed guest addresses on AArch64 have been updated to better support 16k pages, rendering snapshots from older versions incompatible with the new release.

Operators should carefully evaluate the impact of these changes before upgrading. Snapshots taken with previous versions will not be loadable, which could disrupt workflows relying on snapshot portability. Additionally, the stricter MSR handling on KVM may require adjustments to guest configurations to ensure compatibility. Systems using String-based paths for sandbox operations will need code updates to accommodate the new PathBuf requirement. Testing these changes in a staging environment is advisable to identify any operational disruptions.
