v1.0.4: Fix tiptapToMarkdown JsonElement type casting

- tiptapToMarkdown used JsonObject.asMap() which returns Map<String, JsonElement>
- All 'as? String' casts silently failed (JsonPrimitive != String), returning empty
- Now uses Gson TypeToken<Map<String, Any?>> for proper raw type deserialization
- contentToMarkdown now handles Map types directly without serialize roundtrip
