Most single-GPU and small-model deployments do not need 64MB custom
all-reduce buffers. Lowering the default to 8MB reduces unnecessary
shared memory allocation. Tests that require larger buffers now
explicitly set the value.

* [RL] Support chunked part files loading in IPC snapshot strategy
## Motivation
When using IPC snapshot for elastic recovery in RL training, loading a single large pdparams file causes a significant memory spike. This PR refactors `_update_ipc_snapshot` to support loading chunked part files to avoid the memory spike.
## Modifications
Refactored `_update_ipc_snapshot` in `fastdeploy/rl/dynamic_weight_manager.py` with a three-level loading priority:
1. **Chunked part files** (`model_state.tpR{id}.part{N}.pdparams`): Load multiple smaller shards sequentially, freeing memory between each chunk via `gc.collect()` to avoid memory spike.
2. **Single full file** (`model_state.tpR{id}.pdparams`): Legacy single-file loading path (preserved for backward compatibility).
3. **Shared fallback directory** (`/shared_ipc_meta/...`): Oldest legacy fallback path (preserved for backward compatibility).
Also fixed the rank ID in the file name pattern from hardcoded `tp0` to dynamic `paddle.distributed.get_rank()`.
## Checklist
- [ ] Add at least a tag in the PR title.
- [ ] Format your code, run `pre-commit` before commit.
- [ ] Add unit tests. Please write the reason in this PR if no unit tests.
- [ ] Provide accuracy results.
- [ ] If the current PR is submitting to the `release` branch, make sure the PR has been submitted to the `develop` branch, then cherry-pick it to the `release` branch with the `[Cherry-Pick]` PR tag.

* [RL][BugFix] Fix ambiguous model path format and add legacy fallback in IPC snapshot
## Motivation
The previous snapshot file naming `model_state.tp{rank}{id}` concatenated
rank and id without a separator, causing ambiguity (e.g., rank=1, id=234
and rank=12, id=34 both produce `tp1234`). Additionally, after the naming
format is updated, existing checkpoints saved in the old format would fail
to load during elastic recovery, causing unnecessary failures.
## Modifications
- Add dot separator between rank and id in snapshot file name:
`model_state.tp{rank}{id}` → `model_state.tp{rank}.{id}`
- Add Priority 3 legacy fallback to load old-format files
(`model_state.tp0{id}.pdparams`) for backward compatibility during
rolling upgrades
- Update docstring and error message to reflect the new 4-level priority

* [BugFix] Force top_k=1 for greedy decoding when temperature=0
When temperature is set to 0 (greedy decoding), only setting temperature
to a small epsilon is insufficient — the sampling kernel may still pick
non-top-1 tokens. Explicitly set top_k=1 in all processors to guarantee
argmax behavior.
Additionally, add argmax fast-path in top_k_top_p_sampling() under
FD_DETERMINISTIC_MODE to handle non-rejection sampling backends that
ignore top_k parameter.
* Extract greedy decoding from FD_DETERMINISTIC_MODE guard
top_k=1 → argmax is a correctness optimization, not deterministic-specific.
Remove the FD_DETERMINISTIC_MODE guard so all-greedy fast-path and
mixed-batch override work unconditionally.

- Add version field to ModelConfig for model version tracking
- Add connected_decodes to register_info for tracking connected Decode instances
- Add FD_ENABLE_PD_RDMA_EAGER_CONNECT environment variable

* [Feature] Add Triton unified attention kernel for deterministic inference
Add a Triton-based unified extend attention kernel that processes both
prefix (cached) and extend (new) KV tokens through a single kernel with
unified kv_indices, ensuring identical accumulation order regardless of
cache hit/miss patterns.
Key components:
- _fwd_kernel_unified: Triton JIT kernel with online softmax, paged KV
cache support, and causal masking for prefix+extend
- Index building utilities: triton_cumsum_with_zero_prefix,
build_kv_indices_from_block_tables, build_unified_kv_indices,
_scatter_extend_kv_indices_kernel (all CUDA Graph compatible)
- pre_cache_len_concat_triton: GPU-only replacement for C++ op
- Reference implementations (_ref variants) for correctness validation
- Comprehensive tests: kernel correctness, split invariance,
determinism, production-scale, cross-validation
