Summary

• adapt the Host-scope Playwright MCP bundle to upstream DSH 0.1.6-alpha.1 commit 0a15e36e7f82b6ed45af6fa9759f29b40dcd965d / tree 66c4c9c2053c6fcf91ad4e47d85bd77539c0b101
• lock the MCP SDK v2, resource, pagination, cancellation, optional-failure, recovery, PTC, and disposal source seams and exact upstream behavior tests
• preserve @playwright/mcp@0.0.80, --isolated, installed Edge, Host-wide shared-process boundaries, and the immutable merge-gated Release workflow

Verification

• local node --check test.mjs, npm test, all seven exact DSH_CORE_REF source seams, package dry-run, YAML parse, and git diff --check
• GitHub Actions run https://github.com/cloga/dsh-playwright-host/actions/runs/34987262968 is green:
  • all 14 Windows/Linux exact-ref certification jobs passed
  • DSH 0.1.6 MCP v2 contract (Windows) passed, including initialization, tools/no-tools, resources/read/cursors, pagination failure isolation, cancellation, reconnect and cleanup
  • DSH 0.1.6 MCP resource snapshot (Ubuntu) passed, including native/PTC resource discovery, URI templates and reads with the exact native host addon
  • release-ready passed

Blocked

This PR must remain Draft and must not merge or release. The 0.1.5 Desktop Release is accepted immutable and its remote managed Check passes; the remaining external gate is the Windows Ops 0.1.5 repin plus explicit coordinator clearance through cloga/dsh-windows-ops#161.

No live DSH Host, Edge profile, Desktop/Home data, credentials, or replacement server was touched. Browser validation against 127.0.0.1:3080 remains unperformed and requires later explicit authorization.
