Pull request overview

This PR makes atomic-generated-answer styling more consistent by ensuring important shadow parts from nested generated-answer sub-components are re-exported and therefore styleable from the top-level component.

Changes:

• Added exportparts propagation for generated answer thread content and follow-up input so consumers can style deeper parts from atomic-generated-answer.
• Exposed inline-link parts by adding exportparts to generated markdown link output, and updated markdown sanitization to allow the exportparts attribute.
• Added/updated unit tests validating exportparts propagation and sanitizer configuration.

As long as we are sure all those parts need to be exported as part im fine with this. This is a lot of customization though XD

This PR does not export additional parts,
All these parts were previously exported. however when we created new custom elements, we broke these exposure so these parts became no longer customizable.

This PR simply restores, this exposure to allow parts to be customizable again.

The only parts that this PR adds are the 3 inline link parts.
