mini-cleanup post #16487 - we don't need to do the work of scheduling an effect that's already dirty which means it already scheduled its root effect to run
* don't mark_reactions inside decrement, it can cause infinite loops
* revert mark_reactions changes
* preserve DIRTY/MAYBE_DIRTY status of deferred effects
* changeset
* tweak
* - add state changes resulting from an $effect to a separate new batch
- schedule rerunning effects based on the sources that are dirty, not just rerunning them all blindly (excempting async effects which will have run by that time already)
* test
* better fix
* tests
* this fixes the last test somehow

Increment the version to ensure any dependent deriveds are marked dirty when the subscription is picked up again later. If we didn't do this then the comparison of write versions would determine that the derived has a later version than the subscriber, and it would not be re-run.
Fixes#16311Fixes#15888
The prior logic was wrong because it reexecuted when something was clean, but we want to when it's not. The remaining fix was to also check the reactions: If an effect is destroyed and it was the last reaction of a derived then the derived is set to `MAYBE_DIRTY`. We therefore also need to check if the derived still has anyone listening to it, and only then reexecute it.
Fixes#16363
Since #9070 it's prefered to use the "enhance svelte elements" way of doing things. That's so long ago that we can now remove the other option from the docs, and eventually remove the backwards compatibility that still allows the old way of doing things.
Fixes#16134
* Add a warning when the misuse of `reset` in an `error:boundary` causes an error to be thrown when flushing the boundary content
* Prevent uncaught errors to make test fails when they are expected and are fired during template effects flush
* reset should just be a noop after the first call
* correctly handle errors inside boundary during reset
* handle errors in the correct boundary

#16268 introduced a slight regression where the state is not reset completely upon compilation. It did reset warnings but not other state, which meant if file A succeeds but file B fails in the parsing state (before the state was reset for real) it would get wrong filename info. This fixes it by setting the filename at the very beginning.
