Document the end-to-end workflow for using the containerd EROFS
snapshotter with Kata Containers runtime-rs, covering containerd
configuration, Kata QEMU settings, and pod deployment examples
via crictl/ctr/Kubernetes.
Include prerequisites (containerd >= 2.2, runtime-rs main branch),
QEMU VMDK format verification command, architecture diagram,
VMDK descriptor format reference, and troubleshooting guide.
Note that Cloud Hypervisor, Firecracker, and Dragonball do not
support VMDK block devices and are currently unsupported for
fsmerged EROFS rootfs.

Adding the pod annotation config to the doc site. A symlink is created
at docs/pod-annotations.md that points to
how-to/how-to-set-sandbox-config-kata.md so that the URL for this file will be
created at `/pod-annotations`. Also adding brief contrbuting guidelines and
how-to's for running the documentation site locally for local previews.

This document describes the Passthrough-FD (pass-fd) technology
implemented in Kata Containers to optimize IO performance. By bypassing
the intermediate proxy layers, this technology significantly reduces
latency and CPU overhead for container IO streams.

Add missing terms to the spell check dictionary to fix CI failures
for kernel debug documentation:
- eBPF
- dwarves: Linux package with DWARF/BTF tools (pahole) required for
CONFIG_DEBUG_INFO_BTF kernel option
Also fix the casing of "ebpf" to "eBPF" in the kernel README to match
the official naming convention.
