Gahow Wang e3a1d70cf2 Switch from RDMA READ to bootstrap-triggered PUSH ...

RDMA READ (batch_transfer_sync_read) fails on GPU memory because
batch_register_memory only sets IBV_ACCESS_REMOTE_WRITE.

New approach: D sends /push_blocks to C's bootstrap with token_ids
+ D's GPU addresses. C's bootstrap:
1. Looks up matching blocks in synced hash table (640/640 verified)
2. Uses C's TransferEngine.batch_transfer_sync_write to PUSH blocks
   directly into D's GPU memory
3. Returns match count + push status

C's scheduler is still NOT involved (0 GPU compute on C).
The push uses C's worker thread + existing RDMA WRITE path (proven reliable).
