ci-cd docs to name main as the canonical branch, ahead of establishing main from

Registered a 3rd repo-scoped runner on bfe-mpc-0640 (label warden-sdk,
bfe-mpc-0640-warden-sdk) per ADR-0004. It is offline pending the sudo-gated steps
(service install + CPUQuota/MemoryMax cgroup cap + toolchain/python provisioning),
documented in docs/ci-cd.md as a [maintainer] handoff. kernel-build stays dispatch-gated
and passes JOBS=4 as a belt-and-braces resource bound.
