fix(sdk-minimal): make the SDK model argument authoritative

Stop narrowing the standalone DeepSeek adapter to a DSH_MODEL-derived one-entry catalog. The direct adapter already accepts model ids outside its advisory catalog, so retain only the DSH_CONTEXT_WINDOW fallback and let the JSON-RPC initialize model be the single runtime selection.

Remove model mirroring from minimal.py and the packaged smoke. The keyless process now initializes deepseek-v4-pro without DSH_MODEL, while the packaged scenario continues to use its unlisted smoke-model; together they prove both cataloged and arbitrary SDK model arguments reach the adapter directly.

Update the bundle, tutorial, SDK/example references, and owning Agent Notes to keep DSH_MODEL only as minimal.py's optional default input, never as a second value callers must synchronize.

 The standalone [`@deepseek-ai/dsh-sdk-minimal` bundle](../../../../packages/bundle/sdk-minimal/README.md) remains a complete JSON-RPC process composition behind `dsh --profile sdk-minimal`. It mounts SDK startup and JSON-RPC serving, the local PTY and subprocess services required by persistent Bash, `fs-local`, the two tool consumers, and uncompressed JSONL persistence under `$DSH_HOME/sessions`. It does not mount `token-meter`, `compaction-basic`, `fs-sandbox`, or `fs-observation-policy`. Persistent Bash still consumes the profile's danger-full-access sandbox policy; the editor is not confined by that policy.
