Patch Changes

• Add findOne() / SingleResult support to useLiveQuery hook. (#1001)

  When using .findOne() in a query, the data property is now correctly typed as T | undefined instead of Array<T>, matching the React implementation.

  Example:

  const query = useLiveQuery((q) =>
    q
      .from({ users: usersCollection })
      .where(({ users }) => eq(users.id, userId))
      .findOne(),
  )
  
  // query.data is now typed as User | undefined (not User[])

  This works with all query patterns:

  • Query functions: useLiveQuery((q) => q.from(...).findOne())
  • Config objects: useLiveQuery({ query: (q) => q.from(...).findOne() })
  • Pre-created collections with SingleResult

• Updated dependencies [f795a67, d542667, 6503c09, b1cc4a7]:
