Workspace version goes from 1.8.1 → 1.9.0. Internal crate deps that
carry an explicit version (wfe-buildkit-protos, wfe-containerd-protos,
wfe in wfe-deno) are bumped to match.

* wfectl CLI with 17 subcommands
* wfectl validate (local YAML compile, no round-trip)
* Human-friendly workflow names (instance sequencing + definition
display name)
* wfe-server full feature set (kubernetes + deno + buildkit +
containerd + rustlang) on a debian base
* wfe-ci builder Dockerfile
* /bin/bash for run scripts
* ensure_store_exists called on host start
* SubWorkflowStep parent data inheritance
* workflows.yaml restructured for YAML 1.1 shallow-merge semantics
