This PR adds support for interactivity to the combined "try this" messages that were introduced in #9966. In doing so, it moves the link to apply a suggestion to a separate `[apply]` button in front of the suggestion. Hints with diffs remain unchanged, as they did not previously support interacting with terms in the diff, either. <img width="379" height="256" alt="Suggestion with interactive message" src="https://github.com/user-attachments/assets/7838ebf6-0613-46e7-bc88-468a05acbf51" />

# `simp?` in conversion mode
|
|
|
|
Tests that `simp?` and `dsimp?` work properly in `conv` mode: namely, that each displays the
|
|
appropriate suggestion and applies the corresponding simplification to the focused expression.
