Previously, the openshell snap used the ssh-keys interface to get access
to the host's ssh binary, which is used for sandbox connect/exec/forward.
However, ssh-keys is a privileged interface which also grants access to
the public and private ssh keys on the host. As such, it required manual
connection in order to be used.
This weakened the security sandbox of the snap, and hurt the UX of
installing it.
This commit changes this by removing the `ssh-keys` interface and
instead vendoring the `ssh` binary within the snap.
This is safe because OpenShell always invokes the `ssh` binary with
`StrictHostKeyChecking=no`, `UserKnownHostsFile=/dev/null`, and
`GlobalKnownHostsFile=/dev/null`, and never uses any host credentials or
ssh configuration. Openshell only ever access to `~/.ssh/config` to
write OpenShell-managed aliases, and this can safely live within the
snap sandbox, rather than leaking into the host environment.

Add a dedicated page documenting how to run the OpenShell gateway as a
container using docker run, docker-compose, or podman, without the
system package manager installer.
This is useful for users on immutable OS distributions (Fedora CoreOS,
bootc-based images, Silverblue) where the standard install.sh path is
not appropriate, and for container-first environments.
Covers a quick-start with TLS disabled (localhost-bound), a full mTLS
setup using the gateway's generate-certs subcommand, a docker-compose
example, and a Podman variant.
Closes the gap raised in #1285.

* docs(kubernetes): add initial reference docs
Add a Kubernetes reference section under docs/reference/kubernetes/ covering
gateway setup, OIDC and reverse-proxy authentication, cert-manager PKI, and
Gateway API external access. Update installation.mdx to link to the new setup
page and nest the new folder under the Reference section in index.yml.
* docs(kubernetes): promote Kubernetes to top-level nav and retitle pages
Move docs/reference/kubernetes/ to docs/kubernetes/ so the section appears
as a top-level nav entry rather than nested under Reference. Retitle the
pages to broader, action-oriented names (Managing Certificates, Ingress,
Access Control) and rename the files to match. Update cross-references in
setup.mdx and the installation page.
* docs(nav): revert Reference to folder mode
The Reference section was switched to explicit section/contents to host
the nested Kubernetes subsection. With Kubernetes promoted to a top-level
folder, restore folder-mode auto-detection. Side effect: sandbox-compute-drivers
is picked up again, which was silently absent from the explicit list.
* docs(kubernetes): add OpenShift install page
Mirror the OpenShift install instructions from PR #1240 into the
Kubernetes docs section. Documents the SCC binding for sandbox pods
and the chart overrides required by OpenShift's Security Context
Constraints (disabled PKI init Job, plaintext TLS, cleared fsGroup
and runAsUser).
