Yichen Jiang 25b6381c84 fix(web): compose a forked session, and give the shell realm its provider
Two consequences of moving the agent plane behind presets, both invisible
until the host plane stopped carrying model-facing rows.

`sessions.fork` built its child with a bare `installTarget` and a `meta`
without `agentPreset`. That was harmless while every tool sat in the host
plane — the child inherited them for free. It now comes up with an EMPTY
tool set. The child composes the parent's preset instead, for the same
reason a resumed session keeps its own: the seeded history was produced
under those tools.

`bashEnv` lives in its own `dsh-bash-env` row rather than inside
`tool-bash`, so a preset that isolates the realm must compose the provider
beside its consumer; the host row is disabled here like every other
model-facing one. Nothing outside the agent plane injects `bashEnv`, so it
stays per-session.

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.
