I had wrong assumptions: I thought the pipe would be cleared by another
handler, that's clearly not the case.
I rewrote the logic to filter out non text inputs by consuming them, and then
consume those inputs with `ReadFile`.
In https://github.com/llvm/llvm-project/pull/175812#discussion_r2690205275 I
did not filter out the 2 properly.
This fixes the issue and does not put lldb in a busy loop anymore.
