Towards #27676

What does this implement/fix? Explain your changes.

When calling the callback hooks, the callback context now inspects each hook's signature to provide only the necessary args (if available). It also evaluated any args provided as a callable when requested, to enable lazy-loading of any arg.

AI usage disclosure

I used AI assistance for:

• Code generation (e.g., when writing an implementation or fixing a bug)
• Test/benchmark generation
• Documentation (including examples)
• Research and understanding

Any other comments?
