Fix Cookbook download runner for Python 3.11

pewdiepie-archdaemon · pewdiepie-archdaemon · commit 168f593096cc · 2026-07-07T01:56:02.000Z
Avoid backslashes inside f-string expressions when generating Hugging Face install fallback commands. GitHub Actions compileall runs on Python 3.11, which rejects that syntax.

Verified with Python 3.11 feature-version AST parse, CI-scoped compileall, focused Cookbook import tests, and full container pytest: 4515 passed, 4 skipped.
