verso-v1.0.16

Release adding a Display API for inline rich outputs, source file imports, F# variable injection and formatter improvements, and several cross-kernel stability fixes.

New: Display API

• User code can now call .Display(value) or .Display(value, mimeType) during cell execution to emit inline, MIME-typed outputs
• Integrated across all language kernels: C#, F#, Python, JavaScript (Jint and Node), and PowerShell
• DisplayHandler and DisplayFormatterContext resolve formatters and write outputs through the execution pipeline
• Convenience CellOutput factory methods added: Plain, Html, Svg, Png, Jpeg, Gif, WebP, Bmp, Json, Csv, Mermaid, Error

New: Source File Imports

• #!import now supports importing source files (.cs, .py, .ts, etc.) by mapping file extensions to registered kernels
• Magic command lines are extracted and sorted by priority (package directives first, then imports, then other directives) before execution
• Kernel lookup by file extension via FindKernelByFileExtension and GetSupportedExtensions

New: Extension Template Scaffolds

• Optional scaffolds for magic commands, cell types, and themes in the extension template
• Template parameters (includeMagicCommand, includeCellType, includeTheme) control which scaffolds are generated
• Sample implementations and corresponding unit tests included

Improved: F# Variable Injection

• Primitive types (string, int, long, double, float, bool, decimal) are now injected as F#-typed let bindings via EvalSilent, so type-dependent features like printf format specifiers work correctly
• Names that already exist as native FSI bindings are skipped to avoid shadowing
• Non-primitive types fall back to AddBoundValue

Improved: F# Data Formatter

• Collection display limit is now configurable via MaxCollectionLimit (default 100) and wired to kernel settings for runtime changes
• TryFormatAsync is now an instance method so kernel settings are applied during formatting
• VariableBridge.UpdateOptions pushes option changes (e.g., publishPrivateBindings) to the bridge without requiring a kernel restart

Improved: C# Variable Preamble

• BuildVariableStorePreamble now only injects variables that are not already present in the Roslyn script state, preventing type conflicts (e.g., CS0266) when users re-declare a variable with a specific type

Improved: Display Handler MIME Hints

• When a MIME hint is supplied and the value is already a string, the raw string is written directly with the provided MIME type, bypassing the formatter pipeline

Fixed: F# Script Directive Paths on Windows

• Removed forward-slash normalization that broke #I include-path resolution on Windows
• Emit #r, #load, and #I directives using F# verbatim strings (@"...") so backslashes in Windows paths are treated as literal path separators instead of escape sequences

Improved: VS Code Editor Provider

• Host lookup in save/rename/backup flows now uses hostRegistry.getByUri instead of the previous getHostForDocument scanning logic
• BlazorBridge.getDocumentUri() exposes the editor's document URI
