fix: use `state` instead of `source` in reactive classes (#16239)
* fix: use `state` instead of `source` in reactive classes * fix: use `active_reaction` as indication to use `source` or `state` * fix: cleanup `#initial_reaction` on `teardown` to free memory * fix: use `#source` in `set` too * unused * chore: use WeakRef * use update_version instead of WeakRef in SvelteSet/SvelteMap (#16324) * tidy up * tweak comment to remove active_reaction reference --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>pull/16325/head
