- 4a59320: Switch the builder-agent-native-starter sync to the vendor-branch model: a new
push-starter-templateworkflow materializes the post-processedtemplates/chatand pushes it to the starter'stemplatebranch (which the starter git-merges intomain). Removes the obsolete dispatch workflow and thesync-builder-starter-manifestCLI (themerge/generate/pathsallowlist sync), superseded byagent-native template materialize+ git-native merge.
