🐛 fix(common): preserve source quote style

tombi v1.2.0 applies its string_quote_style rule to keys and values,
defaulting to Double, which rewrote literal-quoted keys to basic
strings. Quote normalization is owned by normalize_key_quotes and the
value string logic, so pin tombi to Preserve and leave those decisions
to us.
