Move `load_workspace_dependencies` and the primary-runtime payload logic out
of `apps/desktop-host` into `@deepseek-ai/dsh-tool-workspace-dependencies`
so profiles other than Desktop can mount the same tool. Desktop keeps its
behavior through the package.
Two additions for carriers that are not Electron applications:
- `root` is optional: without it the payload is validated and used in place
(no copy under the Harness home), which suits read-only container layers.
- `runtime.json` accepts `linux`, and the `node` / `pnpm` components are
optional; the returned paths and the tool output omit what the payload
does not ship.
The `sdk` profile mounts the tool and `@deepseek-ai/dsh-skill-office` when
`DSH_PRIMARY_RUNTIME` names a payload directory (its sibling `office-skills/`
carries the skill resources); both rows stay disabled otherwise. Both
packages join the Python runtime closure.
Add a startup-only sdk-minimal template whose sole bundle inserts the complete JSON-RPC agent tree over the empty profile root. The roster is an explicit composition allowlist: it contains one DeepSeek adapter, the minimal agent spine, persistent Bash, the string-replace editor, local execution, and JSONL persistence, while dsh-base and Web remain absent.
Reuse the SDK app startup provider so the new profile retains help, stdin EOF, and bounded launcher shutdown semantics. Make that provider render its configured profile name, which keeps both sdk and sdk-minimal help truthful without duplicating process lifecycle code.
Register the package in the CLI closure, TypeScript graph, lockfile, Knip policy, and bilingual bundle references. Exact manifest, row-roster, profile-template, config-dump, and HMR tests make later additions visible instead of relying on a blacklist.
Introduce @deepseek-ai/dsh-sdk-app as the thin application layer for the built-in sdk profile. The bundle contributes the JSON-RPC server and startup-only profile metadata, while dsh-base continues to own the shared agent, provider, persistence, and tool composition.
Publish ctx.appReady from the launcher only after the Loader tree and launcher-owned setup succeed. The stdio lifetime binding leaves stdin unread until the protocol transport claims it and defers EOF exit 0 until readiness commits, so early protocol frames remain buffered and a racing startup failure remains the nonzero process outcome. Fiber disposal cancels both pending lifecycle listeners.
Register the bundle in the CLI resolver closure, generated configuration catalog, workspace graph, and built-bin smoke. Startup tests prove that base plus sdk-app exposes the SDK server without taking ownership of shared runtime plugins; focused and built-bin regressions cover early input, EOF readiness, and startup-error precedence.
