fix(mtmharness): align DSH dependencies with alpha4

[codeh007]

Summary

• align mtmharness DSH peer and development dependencies with 0.1.2-alpha.4
• regenerate the workspace lockfile and release-age exemptions so profile installs cannot retain the stale alpha3/rc2 graph
• bump mtmharness to 0.9.2 for the corrected package metadata

Root cause

mtmharness@0.9.1 still advertised the DSH alpha.3 dependency graph. A profile using the newer DSH alpha.4 release could therefore load an incompatible/stale dsh-client-connection implementation, producing the reported options.authority failure during ctx.connection.rpc.handle. The type-only import in src/index.ts is erased and is not the runtime cause.

Verification

• pnpm install --frozen-lockfile
• pnpm --filter mtmharness run check (17 Vitest files, 92 tests; 24 Node tests)
• pnpm --filter mtmharness pack
• pnpm dlx publint run .tmp-pack/mtmharness-0.9.2.tgz --strict
• official @deepseek-ai/dsh@0.1.2-alpha.4 isolated web profile booted successfully with mtmharness@0.9.2
