style: fix yapf - inline f-string concat and for-loop continuation indent

- _unsafe_local_code_executor.py: merge two f-string lines into single
  parenthesized expression per yapf preference for adjacent string literals
- __init__.py: indent for-loop body strings to 12 spaces (continuation =
  for-indent + 8) per yapf bracket continuation rule
