Yichen Jiang 2b8a0a8cff feat(web): choose the agent preset on the new-session screen
The composer seat spent nearly all its life disabled: a session's
composition is fixed once a turn has run. Move the choice to the
new-session screen beside the workspace picker, where it still works,
and let the session header report what a running session runs.

The hero pick is staged rather than applied — that screen precedes the
session it belongs to. It lands when a session becomes current and is
still blank, which covers both the session a workspace connect creates
and the blank one it reuses; riding `sessions.create` would miss the
second. It is spent on first use, matching the workspace picker.

Fix the durability the header field claimed but never had: `agentPreset`
was declared on `SessionHeader` and dropped by the JSONL header line, the
SQLite sessions row, the derived query index, and the cold list
projection, so every resumed session came back composed from nothing.

Add the web e2e lane that would have caught it — the one lane that mounts
the shipped roster, which needed `cordis:group` in the scaffold's Loader
builtins, as `mountRootInclude` already registers.

host/ — web-GUI host half

English | 中文

The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in client/; the composed application is apps/cli booting the dsh-base bundle serving apps/web. All product packages.

Package Role ctx key
apiproxy/ Shared host API gateway and wire contract ctx.apiProxy
webserver/ HTTP route carrier ctx.httpServer
frontend-static/ SPA dist server on the webserver fallback seat consumes ctx.httpServer
directory-picker/ Workspace-directory picking seam ctx.directoryPicker
directory-picker-native/ Native directory-picker backend and browser interaction registers ctx.directoryPicker
directory-picker-browse/ In-app directory-browser backend and interaction registers ctx.directoryPicker
directory-picker-auto/ Host-adaptive picker composition mounts a backend

apiproxy remains transport-independent; client/connection supplies the browser/HTTP carrier. Picker implementations replace one another behind the shared seam.
