fix(app): fix custom slash commands not showing on initial /

[Raviguntakala]

Problem

Custom commands (like /init, /review, /commit) were not showing in the slash command menu when first typing /. Users had to type a character and backspace to see them.

Cause

The useFilteredList hook doesn't re-run when sync.data.command loads asynchronously after the initial render.

Solution

Added a createEffect that calls slashRefetch() when sync.data.command changes, ensuring custom commands appear immediately.

Changes

• packages/app/src/components/prompt-input.tsx: Added refetch trigger when commands load
