feat(vscode): support multilingual notebook autocomplete

[markijbema]

Summary

• Enable notebook autocomplete for every language represented in the existing autocomplete language catalog rather than limiting it to Python.
• Build whole-notebook context in the active cell's language, commenting Markdown and foreign-language cells where syntax permits and preserving cursor offsets when content must be omitted.
• Carry the active VS Code language ID through prompt construction so .ipynb paths no longer force Python-specific prompting and filtering.

This follows #11597 and keeps mixed-language notebooks from injecting foreign code as executable context.
