Description

NeXus v2025.11 was just released: https://github.com/nexusformat/definitions/releases/tag/v2025.11

There may be useful changes for us. Even if ECDC don't use them yet, we can use them for outputs.

Notably, BIFROST wants to make use of the new NXcomponent base class and its inputs and outputs members to replace the numbering system in its files. So we should add support for that.

Research direction

Start by reviewing the NeXus v2025.11 release notes and the project's existing NeXus support for base classes and member handling. Trace how output files currently represent numbered components, then define completion as support for NXcomponent with its inputs and outputs without depending on ECDC adoption; the issue names no files or tests to run.
