Pull Request Overview

This PR changes the type of context and dependency_type fields in ExternalItemFnCtx struct from strings to their respective typed equivalents (Context and DependencyCategory). This improves type safety and reduces unnecessary string conversions when creating the context object.

• Changed context field from String to Context type
• Changed dependency_type field from String to DependencyCategory enum
• Updated all references to use the typed values directly instead of string comparisons

[Copilot]

The RawExternalItemFnCtxInner struct now uses typed fields but this change may break the JavaScript/TypeScript binding layer. The raw bindings typically need to convert between Rust types and JavaScript types, and changing from strings to typed enums could require additional conversion logic in the getter methods.
