Pull request overview

Improves AstNodeToScriptAdapter’s “decompiler” output so reconstructed source is parseable and round-trips string/GString values more faithfully, addressing GROOVY-12153’s string rendering issues in the Groovy Console AST-to-script view.

Changes:

• Replace naive string literal escaping with a dedicated single-quoted escaping routine that handles backslashes, quotes, and control characters.
• Rework GString rendering to rebuild from GStringExpression segments/values, properly escaping text segments and emitting safer interpolation forms.
• Add/expand tests to validate string escaping and GString round-tripping, plus update an existing regex assertion expectation to match the corrected escaping.
