Alex Dunmow cc19b7eabb feat: check 31 — bn chrome template sync between cms and core
cms/backend/templates/bn is the authoring source for the bn page chrome;
core/templates/bn carries a mechanically-synced copy for guest-side plugin
templates. Byte-compares the sync set (head/toolbar/engagement templ +
asset_hooks.go) and fails with 'run make sync-templates in cms' on drift.
Skips when the repo has no backend/templates/bn or no sibling core checkout.

// is img.templ (cms-only, not referenced by the chrome).
