Hojun-Cho 79c758c046 test: wire lib/bufio/bufiotest.ww into make test (closes #23)
Closes the coverage gap that hid task #22's pointer-rooted N_DOT bug:
test/wcc/900_stdlib.c claimed "Coverage lives at lib/bufio/bufiotest.ww"
but no test/wcc/*.c ran bufiotest. New 998_bufio_run runs it and
propagates exit; matches 910_at_test pattern.

/*
* 998_bufio_run — execute the lib/bufio @test fixture under the
* C-side `ww run` driver and assert exit 0.
*
* Why this exists: lib/bufio/bufio.ww was lifted out of the
* w6c-compile sweep in 900_stdlib because its cross-module type
* refs only resolve once the driver concatenates `use`d modules.
* That note ("Coverage lives at lib/bufio/bufiotest.ww") was true
* in intent but not in fact — nothing actually ran bufiotest.ww
* under `make test`. Bug #22 (pointer-rooted chained N_DOT) hid
* in that gap. This harness closes it.
*
* bufiotest.ww carries its own `export fn main()` that drives the
* @test fns and signals which case failed via the exit code, so
* this file is just a thin wrapper — no @test scanning, no
* synthetic main generation.
