* feat(templates): add py: lines to command templates' scripts frontmatter Every templates/commands/*.md with a scripts: block now declares a py: variant so --script py renders a Python invocation via the existing interpreter-prefixing in process_template. Fixes #3283 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: install scripts/python for the py script type install_shared_infra mapped every non-sh script type to powershell, so --script py rendered invocations pointing at files that were never installed. Map py to the python variant dir and skip __pycache__ artifacts during the copy. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test: read templates with explicit utf-8 encoding Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: keep py: lines standalone, enforce script existence in tests Drop the plan/tasks py: lines that referenced scripts shipping in the core port (#3280); they move to that PR. Tests now assert every py: line points at a script the repo ships, so a dangling reference can never merge green.
