SCSS `!default` / `!global` inside strings are treated as declaration flags

Prettier 3.8.3

When !default or !global appears inside a string or function argument in SCSS, Prettier treats it as a Sass declaration flag instead of part of the value.

Input:

$a: "!default";
$b: unquote("!default");
$c: url("x!global");

Actual output:

$a: " !default";
$b: unquote(" !default");
$c: url("x !global");

Expected output:

$a: "!default";
$b: unquote("!default");
$c: url("x!global");

This looks like the SCSS directive detection is matching raw !default / !global text before the value is parsed, so values containing those strings get split as if they had trailing Sass flags.

I can send a fix with regression tests.

Reproduce the issue with the three SCSS inputs shown and trace the SCSS directive detection described in the report, especially where raw !default and !global text is matched before value parsing. Add regression coverage for strings, function arguments, and URLs, then confirm the formatter preserves the expected output without inserting spaces.
