fix: properly resolve remote entrypoints when including Taskfiles

[twelvelabs]

This MR fixes the ResolveEntrypoint methods for each of the Node types so that they consistently handle remote URI values.

Notes:

• Not touching HTTPNode, because ResolveReference already does the right thing:

  If ref is an absolute URL, then ResolveReference ignores base and returns a copy of ref.

Fixes: #2437
