Describe the problem

Svelte 4 emits some events in dev mode around elements being inserted etc and provides location info on the elements that map back to the original code.

Svelte 5 currently doesn't have any of it. To support devtools et al, it needs to be added back, ideally in a less on-the-fly way compared to before.

Describe the proposed solution

No good idea yet - first we need to collect requirements from tooling:

• Svelte devtools @ignatiusmb
• Svelte inspector @dominikg
• others who use it, like Kitbook @jacob-8

Importance

nice to have
