/*
 * 909_stof_run — execute the lib/strconv/test/stoftest fixture under the
 * C-side `ww run` driver and assert exit 0.
 *
 * Same thin-wrapper shape as 922_decimal_run: stoftest.ww carries its own
 * `export fn main()` that drives the @test fns (stof64/stof32 DEC + hex
 * vectors, bit-exact) and signals which case failed via the exit code
 * (signalled + 10, so cases 1..4 → exit 11..14).
 *
 * The fixture lives in lib/strconv/test/ (not lib/strconv/) so
 * `import strconv` resolves to the lib/strconv DIRECTORY (full package:
 * strconv.ww + decimal.ww + stof_data.ww + stof.ww), not the strconv.ww
 * FILE — same rationale as 922_decimal_run.
