feat(dsh): add shared harness analysis

Implements #104 using docs/specs/2026-08-24-104-deepseek-harness-shared-analysis-evidence-bundle.md. Qualify DSH for shared Asset Practices, Harness evidence, and Evidence Bundle collection with one frozen canonical cwd while keeping rendering and Checkup out of scope.

Validate the change with Node 22.20.0 and Node 24.15.0 focused suites, native DSH smokes, and a clean npm run check. Existing DSH Session and configured-assets semantics remain unchanged.
