fix(build): arm64 交叉编译补 CXX——「刻意不设 CXX」的注释判断是错的

build.sh 的 linux/arm64 分支此前刻意不设 CXX，注释理由是「设了会让
Go 用 aarch64 的 g++ 去链接，而它对 host 产生的 .o 报 file format
not recognized」。

那个判断是错的。那个报错的真因是 cmd/{homed,waiter}/*.syso（x86-64
COFF Windows 资源对象）被 Go 无条件链进了目标，与 CXX 无关。四组对照：

  syso 在   + 无 CXX → Relocations in generic ELF (EM: 183)
  syso 在   + 有 CXX → 000000.o: file format not recognized
  syso 隐藏 + 无 CXX → Relocations in generic ELF (EM: 183)
  syso 隐藏 + 有 CXX → 成功，ELF aarch64

两个条件缺一不可。之前诊断时只单独试了其中一个，得出错误结论后写进
注释固化了下来，于是 arm64 的 homed 一直编不出（v1.0.0 发布时 arm64
deb 里只有 waiter/initconfig）。

本脚本的 hide_syso_for_target 已处理 syso 那半，这里补上 CXX 那半。
实测 v1.0.1：build.sh linux/arm64 直接产出 ELF aarch64，arm64 的
full/server deb 里 homed 与 waiter 均为 aarch64。

 ## 项目状态
 
+**v1.0.1** — 多模态 bugfix。插件 ABI/协议未变，1.0.0 编出的 `plugin.bin` 无需重编。修三类缺陷：（1）**看图假成功**——媒体块挂在 tool message 上不被模型当作可视内容（实测同一张图：tool message 0/3 读到、独立 user message 3/3），改为另起一条紧随其后的 user message 承载，落实插件文案一直在说的「注入后续对话」；（2）**新增多模态能力声明与回退链**——`core.llm.sources.<name>.vision/.audio` 声明源能否真正处理媒体（网关会静默剥离 `image_url` 后仍返回 200，带图与不带图 prompt_tokens 完全相同），不支持时自动走视觉源转写成文字，并落实了 `core.input_processing.image.fallback_provider` 这批早已注册却从未被读取的配置项；（3）**`see_video` 帧数语义反了**——`fps=1/N` 是频率不是数量，20s 视频请求 10 帧只得 2 帧、请求 1 帧反得 20 帧，改为 `ffprobe` 取时长 + `fps=N/时长` + `-frames:v` 硬封顶。
+
 **v1.0.0** — 外部插件从 C ABI 动态库迁移到**子进程 + 共享内存**。首个不再加载 `.so`/`.dll` 的版本，与 0.9.x 不兼容（存量插件须用新版 `plugindev` 重编为 `plugin.bin`，**业务代码零改动**）。消除 6 类此前在生产造成故障的缺陷：热重载失效（`DF_1_NODELETE` 让 `dlclose` 成 no-op）、崩溃隔离缺失（插件 panic 带崩 homed）、stage lost update（副本模型丢失 35.8~36.8%）、cgo 超时不可中断（线程线性泄漏）、`output_send` 假成功（模型收到「已发送」而消息未送达）、Windows 能力断层（只见 3 个 stage 字段且无法写回）。三面通信：stdio JSON-RPC（控制）+ 共享内存段（数据）+ 事件环（通知）；权限梯度显式化为三道闸。RPC 往返 p50 24.1µs，崩溃到恢复 <1s。
 
 **v0.9.0** — C ABI v2：外部插件 Stage 回调支持写回（`invoke_stage` 增加 result 输出，插件可在 OnInput/AfterToolcall/PostAction 修改 RawMessage/LLMText/ToolResults 等并同步回内核），ABI 版本随内核 minor 对齐（v0.9.x → ABIVersion=2，`version_min=1` 向后兼容旧插件）。同步修复工具循环 zen 兼容补位误伤首轮 system 上下文的问题。配套 SDK 提供增强版 sanitizer 示例（坏 UTF-8/U+FFFD/ANSI 转义全链路清洗）。**该 ABI 已随 v1.0.0 退场。**

 ## Project Status
 
+**v1.0.1** — Multimodal bugfix. The plugin ABI/protocol is unchanged, so `plugin.bin` artifacts built for 1.0.0 need no rebuild. Three defects fixed: (1) **vision silently failing**—media blocks attached to a tool message are not treated as viewable content by the model (measured on one image: 0/3 read from a tool message, 3/3 from a standalone user message); media now rides its own user message placed immediately after, which is what the plugin's own wording ("injected into the following conversation") always claimed; (2) **new multimodal capability declaration + fallback chain**—`core.llm.sources.<name>.vision/.audio` declares whether a source can genuinely process media (a gateway may strip `image_url` and still return 200, with identical prompt_tokens with and without the image); when it cannot, media is transcribed to text via a vision-capable source, finally wiring up the long-registered but never-read `core.input_processing.image.fallback_provider` settings; (3) **`see_video` frame-count semantics were inverted**—`fps=1/N` is a *rate*, not a count, so a 20s video yielded 2 frames when 10 were requested and 20 frames when 1 was requested; now `ffprobe` measures duration and the filter becomes `fps=N/duration` with `-frames:v` as a hard cap.
+
 **v1.0.0** — External plugins moved from C ABI shared libraries to **subprocess + shared memory**. The first release that no longer loads `.so`/`.dll`, and it is incompatible with 0.9.x (existing plugins must be rebuilt into `plugin.bin` with the new `plugindev`, though **business code needs zero changes**). Eliminates 6 classes of defects that had caused production incidents: hot-reload silently failing (`DF_1_NODELETE` making `dlclose` a no-op), no crash isolation (a plugin panic took down homed), stage lost updates (35.8~36.8% loss under the copy model), uncancellable cgo timeouts (linear OS-thread leaks), `output_send` reporting false success (the model was told "sent" while the message never went out), and Windows capability degradation (only 3 stage fields visible, no write-back). Three communication planes: stdio JSON-RPC (control) + shared memory segment (data) + event ring (notification); the privilege gradient is now enforced by three explicit gates. RPC round-trip p50 24.1µs; crash-to-recovery under 1s.
 
 **v0.9.0** — C ABI v2: external plugin Stage callbacks can now write back (`invoke_stage` gained a result out-param; plugins may mutate RawMessage/LLMText/ToolResults etc. in OnInput/AfterToolcall/PostAction and have them synced to the core). ABI version now tracks core minor releases (v0.9.x → ABIVersion=2, `version_min=1` keeps old plugins loadable). Also fixes the tool-loop zen-compat placeholder that wrongly fired on first-turn system context tail. The SDK ships an enhanced sanitizer example (bad-UTF-8 / U+FFFD / ANSI-escape scrub across the whole pipeline). **This ABI retired with v1.0.0.**
