feat(test): add synthetic policy generation and tests

[ZGZ713912]

摘要

新增合成策略生成与运行时测试，并调整策略服务和 RL 桥接实现。

• test/gen_synthetic_policy.py 直接生成零动作 ONNX 策略，不再依赖 PyTorch。
• 新增 test/runtime_test.cpp，覆盖观测历史、发布时间线、动作通道并发读取和策略归一化。
• 新增 test/test_layout.py 自测布局解析、签名、哈希和参数校验；布局契约脚本改用独立临时目录。
• CI 启用 BUILD_TESTING，运行 rmcs_rl 测试，并将 test/** 纳入 PR 路径过滤。
• 新增 PolicyModel 和 OnnxRuntime，集中处理模型元数据、布局校验、归一化、裁剪和推理。PolicyServer 改用 PolicyModel。
• 新增 BridgeConfig、ObservationHistory 和 ObservationTimeline，将参数加载、观测历史及时间序列管理从 RlBridge 中拆分。
• 移除旧 ONNX 推理头文件、执行器配置和 tool/gen_drive_policy.py；更新 README 和相关构建配置。

测试

新增了 C++ 运行时测试和 Python 布局自测。未提供测试执行结果。

Walkthrough

本次变更重组桥接器的配置、观测历史和时间线处理，并新增策略模型与 ONNX 推理封装。项目增加运行时和布局契约回归测试，并更新 CI、部署文档及安装规则。

Changes

运行时与部署

Layer / File(s)	Summary
桥接配置与观测组件 include/rmcs_rl/rl_bridge/config.hpp, src/rl_bridge/config.cpp, include/rmcs_rl/rl_bridge/observation_history.hpp, src/rl_bridge/observation_history.cpp, include/rmcs_rl/rl_bridge/observation_timeline.hpp, src/parameters.cpp, src/rl_bridge/joint_config.cpp, CMakeLists.txt	新增 BridgeConfig 加载及观测历史、时间线组件。配置加载会校验动作映射、观测尺寸、历史长度、频率和动作年龄等参数。参数实现移至 src/parameters.cpp。
桥接运行时接入 src/rl_bridge.cpp, include/rmcs_rl/rl_bridge/action_channel.hpp, src/rl_bridge/action_channel.cpp, include/rmcs_rl/rl_bridge/types.hpp, src/rl_bridge/interface_binding.cpp	RlBridge 改用集中配置和观测组件处理发布调度、序号及动作时效。ActionChannel 改用互斥锁保护动作快照。使能值现在必须为有限且非零的数值。
策略模型与推理服务 src/policy/onnx_runtime.hpp, src/policy/onnx_runtime.cpp, src/policy/policy_model.hpp, src/policy/policy_model.cpp, src/policy_server.cpp, include/rmcs_rl/onnxruntime_inference.hpp, CMakeLists.txt	新增 ONNX 模型校验、元数据读取、归一化及裁剪实现。PolicyServer 将推理交给 PolicyModel，并从模型信息构建状态消息。旧的 OnnxRuntimeInference 头文件被删除。
回归测试与 CI test/runtime_test.cpp, test/test_layout.py, test/test_layout_contract.sh, test/gen_synthetic_policy.py, tool/rl_layout.py, tool/gen_drive_policy.py, .github/workflows/ci.yml, CMakeLists.txt, package.xml	新增桥接组件、并发动作快照、策略模型及布局契约自测。CI 启用 BUILD_TESTING 并运行运行时测试和布局契约脚本。合成策略脚本改为直接生成 ONNX 测试策略。
部署配置与文档 README.md, config/executor.yaml, CMakeLists.txt	README 改为部署包使用说明，并记录现有 deformable 模型缺少布局元数据。删除 config/executor.yaml，安装规则改为安装 launch 目录。

Merge Risk: 🟡 Moderate · up to c03cc

Concurrent action delivery can briefly interrupt otherwise valid control output. Preserve the last successfully read action, subject to its existing freshness check, before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to c03cc

The change reorganizes a path that can produce control outputs. The reviewed checks still reject mismatched, stale, and invalid data, and no introduced security failure was established. Publisher access and deployment behavior remain insufficiently documented to rate the overall design risk as minimal.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Within an affected bridge instance, the sensitive outcome is its configured action-output interfaces. Observation and action topics are upstream inputs, but the available evidence does not establish which external processes or environments can publish to them.

Trust Boundaries and Controls

• observed — The policy path rejects a mismatched layout, model-dimension errors, and non-finite inference results before publishing; the bridge independently checks action identity, age, sequence, and values before valid control output. These are data and compatibility checks, not evidence of publisher authentication.

Resilience and Maintainability Implications

• observed — The mutex makes action fields a coherent snapshot. A failed nonblocking read does not mark the previous snapshot valid, and a detected contract mismatch remains latched against subsequent valid output.

Hardening Proposals

• proposed — Where deployment permits other processes to publish on control topics, explicitly restrict publisher authority; layout hashes and model IDs should not be treated as proof of publisher identity. This is a deployment hardening proposal, not an established regression in this PR.

- Around line 26-34: ActionChannel::try_read returns false on mutex contention
even when the caller has a previously read snapshot. Track whether a snapshot
has been read, return true on lock contention when one exists without modifying
the caller’s snapshot, and reset that state in resize; continue returning false
before any snapshot has been read.
