fix(qwen3-tts-cpp): hold qwentts.cpp at 35ebe537, upstream master hangs in synthesis (#11286)

Browse Source 
tests-qwen3-tts-cpp has been failing on master since 2026-07-31. The suite
loads every component fine and then stops: TTS() never returns from the
native call, so a job that takes ~5 minutes runs into the 20 minute Go test
timeout instead.

    goroutine 74 [syscall, 19 minutes]:
    github.com/ebitengine/purego.RegisterFunc.func4
    qwen3-tts-cpp.(*Qwen3TtsCpp).TTS  goqwen3ttscpp.go:154
    qwen3-tts-cpp.init.func2.4        e2e_test.go:90

Not a flake: reproduced on master and again on an explicit re-run.

Bisected across this cycle's eight qwentts.cpp bumps by their own check:
10832, 10850, 10902, 10964, 11006, 11039 and 11127 all pass in ~5 minutes;
11241 (abab6b3) fails at 1h58m. That PR was merged with this check already
red, which is how the hang reached master.

35ebe537..abab6b3 is three upstream commits, and the only functional one is
26dd8adb, "predictor: unroll the frame into one cgraph and sample in standard
ops", which is consistent with a generation loop that never reaches its stop
condition.

Hold the pin at the last known-good commit. The bump entry is commented out
rather than left in place, because it tracks upstream master and would put
the hang straight back on the next nightly run. Both spots carry a pointer to
the other so the hold is discoverable, and restoring it is uncommenting four
lines once upstream is fixed.
