Multiple inputs in a query can cause render flicker

[ItsMeBrianD]

When multiple inputs are used in a single query, and they are modified in quick succession, this can cause the query to quickly move through different states, especially when they are cached.

Example Query:

SELECT
    '${inputs.one}' as a,
    '${inputs.two}' as b
    '${inputs.three}' as c

Input store updates are atomic (e.g. one update = one modified input value), so if all 3 inputs here are modified, the query will go through each state, briefly. We attempt to mitigate this by using createReactive, which includes change indexing. The observed behavior is actually that the queries are pulled from the cache, so they are already fetched, and the change indexing isn't applicable.

Debouncing is one potential option but we need to make sure that doesn't introduce perceived latency because all query updates will now be delayed by that amount (unless a leading debounce is used)
