[Debugger] Feature request: “View string as document” for multiline strings

[MistaTwista]

Is your feature request related to a problem? Please describe. When debugging Go code, long string variables are rendered as a single escaped line (\n, \t, etc.) This makes multi-line content, like templated Go code hard to read and reason about

Describe the solution you'd like Add a context-menu command like “View string as document…” for string variables.

Selecting it would:

• Open the value in a new editor tab
• Show real line breaks instead of escape sequences
• Let the user pick a language mode so built-in syntax highlighting applies

Describe alternatives you've considered

• Expanding the inline viewer: still shows escaped characters and wrecks layout
• Copy-pasting into a new file: slow and breaks debugging flow
• External pretty-print tools: require context switching and lose debugger context
• Add functions to render files in FS
