fix: fixes issue where the autocomplete tui dialog flickers while typing

[jcampuza]

Fixes #11640

What does this PR do?

I noticed that when typing @ and / commands in the opencode TUI that you would see the dialog flickering as you type. This is especially true when you type pretty fast here. (For example while typing you'd see the Opencode logo flicker behind as the dialog opens and closes rapidly

This PR fixes that issue by making sure to only update the search value after the value of the filter has settled (i.e. has been flushed due to how Solid works). The issue was caused because the filter depends on both the value (reactive) and non-reactive values that need to be flushed (the input ref/cursor)

Here is the "before" state with the flickering: NOTE that due to framerate you might not see it as well as you would locally well here.

How did you verify your code works?

I tested manually. GIFS below of after state

Note: PR updated with better assets, but still framerate may make it difficult to see at times.

Suggestion: The two if statements on lines 136-143 can be combined since they both do the same thing (setSearch("") and return). Since undefined and "" are both falsy, you could simplify to:

Suggested change

	createEffect(() => {
	const next = filter()
	if (!next) {
	setSearch("")
	return
	}
	setSearch(next)
	})

This is just a suggestion for cleaner code - the current implementation is functionally correct.

Minor typo in comment: "have/render" appears to be a copy-paste artifact. Consider fixing to make the comment clearer (e.g., "...after reactive updates, render, and paint have been applied...").
