Stable Argument Mapping

[scoop1120]

This pull request updates the way argument sequences are constructed for Deno GraphQL resolvers, improving how non-injected arguments are passed to Deno operations. The main change is the addition of a stable argument map as a final argument, which helps maintain positional argument integrity while providing Deno resolvers with a consistent view of all non-injected arguments.

Argument handling improvements:

• The function now appends a final Arg::Serde object containing all non-injected arguments as a single serde_json::Value::Object, making argument access more stable for Deno resolvers.
• Refactored the argument resolution stream to assign its result to resolved_args, supporting the new logic for adding the argument map.
