rem Vendor a trimmed Playbook snapshot into a target project (offline copy),
rem then run sync_standards to materialize .agents\<lang>\ and .gitattributes in
rem the target project root.
rem
rem Usage:
rem   scripts\vendor_playbook.bat <project-root>             (default: tsl)
rem   scripts\vendor_playbook.bat <project-root> tsl cpp
rem   scripts\vendor_playbook.bat <project-root> --langs tsl,cpp
rem   scripts\vendor_playbook.bat <project-root> tsl cpp --apply-templates
rem
rem Options:
rem   --apply-templates   Apply CI/lang templates to project root (skip if exists)
rem
rem Notes:
rem - Snapshot is written to: <project-root>\docs\standards\playbook\
rem - Existing snapshot is backed up before overwrite.
rem - With --apply-templates, CI and lang templates are copied to project root.
