The provisioner was unconditionally writing CLAUDE_CODE_OAUTH_TOKEN into
config.yaml's required_env for all claude-code workspaces. When the
baked token expired, preflight rejected every workspace — even those
with a valid token injected via the secrets API at runtime.
Changes:
- workspace_provision.go: remove hardcoded required_env for claude-code
and codex runtimes; tokens are injected at container start via secrets
- workspace_provision_test.go: flip assertion to reject hardcoded token
