oobabooga d0c5cf6e07 Fix diffusion flag leak, sd-cli orphan, and native family fallback 
Six correctness fixes to the diffusion stack, found reviewing the merged
phase PRs on this branch:

- load_pipeline: restore the try/finally guard around the speed/quant/
  placement span. A failure after apply_speed_optims (e.g. OOM in quant or
  the memory plan) left TF32/cudnn flags flipped process-wide and the
  half-built pipe resident in VRAM. Now restores the flags and frees VRAM
  on a failed load.
- sd-cli Popen binds to the parent (PR_SET_PDEATHSIG via child_popen_kwargs,
  matching the llama.cpp sites), so a parent crash mid-generation can't
  orphan it holding VRAM/RAM.
- Native begin_load uses the filename-fallback family detector the route
  validated with, so a local .gguf whose family keyword lives only in the
  basename no longer dead-ends 400 on a no-GPU host.
- Generate error handler matches exact sentinel messages instead of the
  "cancelled" substring, fixing a 409 misroute and a raw sd-cli output leak.
- find_sd_cpp_binary honors UNSLOTH_STUDIO_HOME/STUDIO_HOME like the
  installer, so a custom Studio home resolves.
- Drop the redundant _tf32_prev bookkeeping; snapshot/restore_backend_flags
  is now the single owner of the TF32/cudnn restore.

The two client-state messages are now shared constants so the 409-vs-500
contract can't drift. Adds a regression test for each behavioral fix.
