docs(agent-note): flip the regrouping note to implemented

Move the triplet to implemented/architecture/, rewrite Proposal into a
present-tense Decision, fold Acceptance criteria and Risks into
Consequences (recording what pins the result), retitle the migration
section to what the move actually touched, and repoint the seven
inbound FIXME/README links.

 ## Config discovery
 
-The first non-empty channel wins: `$DSH_CORDIS_CONFIG`, then positional `argv[2]`. If neither names an existing file, the bin prints one-line usage to stderr and exits 1; there is no working-directory or built-in fallback. [`dsh-app-boot`](../../ui/app-boot/README.md) makes plugin load failures fatal. This protocol does not use `DSH_SNAPSHOT`.

 A config without `dsh-jsonrpc` is valid and serves nothing; the bin does not designate a server plugin.

-只包含 bin 的应用，启动外部 `cordis.yml`；其 [`jsonrpc`](../../ui/jsonrpc/README.md) 入口通过按换行分隔的 stdio 为 SDK 客户端提供服务。配置负责组合主干、后端和服务插件。发布的 bin 名为 `dsh-jsonrpc-agent`，`lib/bin.js` 还会作为 Python SDK 使用的 `dsh-jsonrpc-agent-pkg` [单文件可执行运行时](../../../.agents/notes/implemented/architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md)交付。

 ## 配置发现
 
-第一个非空通道生效：先 `$DSH_CORDIS_CONFIG`，再位置参数 `argv[2]`。如果二者都没有指向现有文件，bin 会向 stderr 打印单行用法并以 1 退出；没有工作目录回退或内置回退。[`dsh-app-boot`](../../ui/app-boot/README.md) 会使插件加载失败成为致命错误。此协议不使用 `DSH_SNAPSHOT`。

 不含 `dsh-jsonrpc` 的配置仍然有效，只是不提供任何服务；bin 不会指定服务器插件。
