run maps the flags onto RunOptions, promotes the first read-write share
to the workspace, inherits stdio, and exits with the guest's code; probe
reports what a run would find (KVM, libkrun loadability with the
remediation, nested virt, cache writability) and fails when a run
would. T6, the no-mount audit, lives here where the binary is built,
ignored behind ECROU_BIN for CI.
ecrou's workspace starts from ecr's confinement-neutral half: image
reference resolution, the content cache with digest freshness, layer
extraction with whiteouts and deferred directory modes, provisioned
hot cells, and the progress/error/config plumbing. Adaptations: the
cache lives in ~/.cache/ecrou, the namespace-era error variants and
utils constants are gone, KvmUnavailable arrives ahead of its caller,
rootfs loses its exec() delegation, and uname(2) goes through libc
now that nix is no longer a dependency. The CLI crate is a stub until
its commit.
