Wave 5+6: plugin ABI hardening, build modernization, ABI/security docs

Wave 5 (9 parallel agents):
- W1.1 atomic diag callback + DLL handle release on shutdown (lin)
- W2.1 unify cross-DLL heap discipline (host->alloc/free/strdup) (chen)
- W2.2 secure_zero api_key on shutdown for deepseek/anthropic (cao)
- W3 CMake modernization: target-based cxx_std_20, dstalk_boost_config
  INTERFACE lib, root-level RUNTIME_OUTPUT_DIRECTORY (hu)
- W4 GitHub Actions CI with dynamic Linux/Windows matrix (ma)
- W5.1 SSE buffer_body to cut peak memory ~67% on 32K streams (zhou)
- W6.1 LSP JSON-RPC frame parser hardened against header reordering (sun)
- W7 smoke test: copy plugin DLLs post-build + Boost.JSON src.hpp fix
  for full 9-plugin load coverage (wang)
- W8.1 README slimmed 398->92, Diataxis docs/ skeleton (deng)

Wave 6 (6 parallel agents):
- W9.1 docs/explanation: architecture + plugin-lifecycle (deng)
- W9.3 log credential leak audit (0 vulns, audit trail in
  docs/explanation/security-logging.md) (cao)
- W9.4 docs/reference/plugin-abi.md - 7-point ABI contract (lin)
- W9.6 CLI /history command + status integration (zhao)
- W9.8 plugin_loader fault tolerance: per-plugin failure no longer
  aborts dstalk_init (huang)
- W9.10 host_api unit tests: tests/host_api_test.cpp, 8 cases (liu)

CEO oversight (preexisting bugs fixed during Wave 5 verification):
- lsp_plugin.cpp:449 forward decl mismatch (int vs void)
- tools_plugin.cpp:109 missing forward decl

Multi-agent collaboration framework:
- agents/WORKFLOW.md: 6-stage protocol, two-tier governance,
  prompt template, technical constraints registry

Build: cmake --build 0 error / 0 warning. Tests: 2/2 100% pass.

工程师

沉稳细致，喜欢读源码，对内存和指针操作有近乎洁癖的关注

10年 C/C++ 系统编程经验，长期在嵌入式和高性能服务领域。熟悉 STL 内部实现、move 语义、PIMPL、ABI 兼容性细节。偏好：能用栈不用堆，能用值不用指针，能用 const 不用非 const。

简洁，喜欢用反例展示问题

C++ 现代特性（C++17/20/23）

内存管理与所有权

PIMPL / ABI 稳定接口

性能调优

偶尔过度强调零开销，忽略可读性

不擅长 UI 相关工作

W2.1 - 修复 file_io_plugin 跨 DLL 堆释放风险 (曹武安全审计 + B3 评审)

success

问题: file_io_plugin.cpp 用 ::malloc 分配，调用方 smoke_test 用 std::free 释放 -- Windows /MT 下不同堆必崩

CRT 类型: /MD (MultiThreadedDLL, 动态 CRT 共享) -- 当前不会崩但违反 ABI 纪律

修复: file_io_plugin 改用 g_host->alloc / g_host->free (host_api 提供的统一分配器)

同步修复: tools_plugin.cpp:58 std::free -> g_host->free (同模式)

同步修复: session_plugin.cpp:166 std::free -> g_host->free (同模式)

同步修复: smoke_test.cpp 三处 std::free -> dstalk_free (与 main.cpp:110 一致)

编译: 0 error; 测试: smoke test passed

发现: initialize_all() 在首个插件失败时停止，使后续插件无法初始化 (预存 bug, 非本次引入)

发现: deepseek/session 插件 Boost JSON 链接错误 (预存问题, 与本次修复无关)
