fix: use f-string for browser query so default_limit is interpolated (#110)

The browser-related query block in fullDesktopQuery used a plain
triple-quoted string instead of an f-string, so {default_limit} was
passed as a literal string to the query engine rather than being
replaced with 100.

The base query block above already used an f-string correctly for
the same variable.
