With a repository host configured (OMARCHY_REPO_HOST / .repo-host), release,
build, sign, promote, update, clean, advance, bootstrap-rc, remove, sync, and
migrate exec on the host over ssh — same code, run where the published tree
lives, after sourcing the host credentials and a --ff-only pull. --local
forces local execution. list/push/deploy/setup never forward. The host itself
has no .repo-host, so ssh'd-in manual use is unchanged. omarchy-release's
advance now rides the same forwarding (one code path), and --host exports
OMARCHY_REPO_HOST so child bin/repo calls follow it.
This closes the gap where bootstrap-rc ran against a workstation's stale
local tree despite .repo-host being set.
