The sync $effect on the home page unconditionally overwrote the local `q`
state with the URL value after every navigation. When users typed faster
than a navigation round-trip (debounce fires → goto() → data reloads),
the completed navigation wrote the stale URL value back into the input,
dropping the characters typed in the interim.
Guard the `q` assignment in the effect with a `qFocused` flag (set via
onfocus/onblur on the text input). Covers issue #34.
