Jiyang Liu 437eae89d6 [feat] add MPS support for Apple Silicon
On macOS there's no CUDA, so these trainer scripts fall back to CPU. Detect MPS in the --device default and switch mixed precision to the device-agnostic torch.autocast / torch.amp.GradScaler so it works there.

CUDA and CPU paths are unchanged.

[fix] PPO: align mb_resp_logp with old_resp_logp under autocast to stabilize training

FloatFrank 1191fc8e9f [fix] PPO: align mb_resp_logp with old_resp_logp under autocast
Move log_softmax for mb_resp_logp inside autocast_ctx so it is upcast
to fp32, matching the rollout path (compute_per_token_logps runs under
no_grad+autocast). Previously log_softmax ran outside autocast on
fp16/bf16 logits, introducing a ~1e-2 systematic bias between
mb_resp_logp and old_resp_logp, so ratio != 1 and KL != 0 even before
any weight update. Under sparse rule-based rewards (e.g. math PPO)
this bias destabilises training.

Also add:
- --rollout_eval_mode (default 1): switch actor to eval during rollout
  to disable dropout and keep old/new logp consistent.
- --debug_log_ratio: optional diagnostic printing |mb-old| on the first
  minibatch to verify ratio ~= 1.
