fix(agent-presets): declare the selected event on the unified session types entrypoint

The persistence catalog recognizes augmentations of
'@deepseek-ai/dsh-session/types' alone, so the old root-specifier
declaration compiled but silently vanished from the generated catalog; the
Agent Note also drops its internal repository link for the public-links
gate, and the persistence catalog pair re-records with the restored
agent-preset section.

 ## Problem
 
-The agent-preset stack moved the whole skill capability — registry, local provider, and the `skill` tool — into each preset's `isolate` realm, because "which skills an agent has" is an agent-plane choice. That framing conflated two different questions: which skills a *deployment* supplies, and whether an *agent* consumes them. A repository plugin's prepared wrapper declares `inject: ['skills']` and mounts its skill root as a host-plane provider; with no host registry composed in the web and headless profiles, that wrapper waited forever and the repository-plugin e2e hung, which [was bypassed by dropping the fixture's skill root](https://github.com/deepseek-harness/deepseek-harness/pull/1538). A per-preset realm registry also made the gateway's skill listing depend on a live agent — a cold session's `/` popup had no registry to read at all.

 The tools registry never had this problem: it is one host singleton layered per scope over `dsh-scope`, so deployment-level tools (MCP servers, plugin entries) register globally while a preset's rows register into that preset's layer.

 ## 问题
 
-agent-preset stack 曾把整个 skill 能力——注册表、本地提供方和 `skill` 工具——搬进每个 preset 的 `isolate` realm，理由是"agent 拥有哪些 skill"属于 agent 平面的选择。这一框架混淆了两个不同的问题：*部署*供给哪些 skill，与*agent*是否消费它们。repository 插件的 prepared wrapper 声明 `inject: ['skills']` 并把它的 skill 根目录挂载为宿主平面的提供方；web 与 headless profile 不再组合宿主注册表后，该 wrapper 永远等待，repository-plugin e2e 因而挂死，[当时通过删掉 fixture 的 skill 根目录绕过](https://github.com/deepseek-harness/deepseek-harness/pull/1538)。按 preset 的 realm 注册表还让网关的 skill 列表依赖存活 agent——冷会话的 `/` 弹窗根本没有注册表可读。

 工具注册表从未有过这个问题：它是一个宿主单例，基于 `dsh-scope` 按 scope 分层，因此部署级工具（MCP 服务器、插件 entry）注册进全局层，preset 的行注册进该 preset 的层。
