Interpolated strings must not be frozen

2025-07-22T15:10:55+00:00

Strings concatenated with backslash may end up being frozen when they
shouldn't be.  This commit fixes the issue.  It required a change
upstream in Prism, but also a change to the Prism compiler in CRuby.

[ruby/prism] Clear flags on interpolated strings

2025-07-21T23:04:42+00:00

When inner strings aren't frozen, we need to clear the flags on
interpolated string nodes so that we don't emit wrong instructions.

The compiler is currently incorrectly emitting frozen strings because
the parser is erroneously declaring interpolated strings as "frozen".
We need to fix this behavior in the parser so we can fix the compiler in
CRuby.  This patch is a partial fix for [this bug](https://bugs.ruby-lang.org/issues/21187)
