@deepseek-ai/dsh-home

@deepseek-ai/dsh-home is the single owner of DeepSeek Harness home-directory resolution. resolveDshHome(configured?) returns an absolute path using this precedence:

1. The explicit configured path.
2. The DSH_HOME environment variable.
3. The .dsh directory under the current user's home directory.

The resolver reads its inputs at call time. It does not cache a result, create the directory, or mutate process.env; consumers keep ownership of their own configuration fields and pass the configured value when resolving the shared home.
