🐛 Fix Argument Parameters with Dynaports

[MFA-X-AI]

Description

This PR fixes a TypeError: 'InArg' object is not subscriptable error that occurred when using dynamic ports (dynalist/dynatuple) with indexed connections to Argument parameters in Xircuits workflows.

Previously, when the compiler generated code for dynamic ports connected to Argument parameters at specific indices, it would fail because InArg objects didn't support subscript operations. When users tried to connect Argument parameters to specific indices of dynamic ports (e.g., dlist[1].connect(self.test2)), the generated code would throw a TypeError: 'InArg' object is not subscriptable.

This PR implements two changes:

1. Added subscript support to InArg class (base.py): Implemented getitem and setitem methods with an _IndexProxy helper class to enable indexed access and connection syntax like port[i].connect(other_port).

2. Updated code generation for dynamic ports (generator.py): Changed from bulk assignment to per-element indexed operations that generate proper code for Argument parameters (.connect()), component references (.connect()), and literal values (direct assignment).

So previously given a workflow like this:

The incorrect generated code would look like:

        self.c_0.dlist[1].connect(self.test)
        self.c_0.dlist.value = ['hello ', 'there']

Error Code:

File ~/Github/xircuits/untitled.py:15, in untitled.__init__(self, id)
     13 self.c_0 = DynaPorts()
     14 self.c_0.__id__ = '7696ed2a-6079-4714-a484-4570d9c2dbac'
---> 15 self.c_0.dlist[1].connect(self.test)
     16 self.c_0.dlist.value = ['hello ', 'there']
     17 self.c_0.next = None

TypeError: 'InArg' object is not subscriptable

With the new this PR:

        self.c_0.dlist[1].connect(self.test)
        self.c_0.dlist[0] = 'hello '
        self.c_0.dlist[2] = 'there'

Output:

Xircuits is running...

• This change requires a documentation update

Tests

1. Dynamic Port with Argument Parameter Test

1. Create a Xircuits workflow with a component that has dynalist ports
2. Add two literals and one argument. Connect the argument so it is in the middle of the literals (like in the example above)
3. Compile and run the workflow
4. Verify that no TypeError occurs during execution
5. Verify the Argument values are properly passed at runtime and is in the correct position

This looks ok at first glance, but I'm wondering if the recurring problems with dynalists may hint at a design problem. We should keep that in mind as we approach further development.
