This prepares 2.0.0-preview.5, following the same steps as the preview.4 prep (#2444). It does not publish anything.

What changes

• Root, SDK and CLI move to 2.0.0-preview.5 in lockstep. The CLI requires SDK >=2.0.0-preview.5. The lockfile also gains the SDK's optional @anthropic-ai/claude-agent-sdk peer metadata, which dev's lockfile was missing.
• All 27 pending changesets are drained into packages/squad-sdk/CHANGELOG.md and packages/squad-cli/CHANGELOG.md (6 minor and 16 patch entries per package). Two of them were folded in by hand from fix(claude): don't project Copilot's template Init Mode skills #2504 and fix(coordinator): a user's team decision reaches decisions.md in the same turn #2505, which removed theirs because of the changeset-drift limit.
• CHANGELOG.md gets ## [2.0.0-preview.5] - 2026-11-14, with the Claude Code section that was waiting in Unreleased. whatsnew.md gets v2.0.0-preview.5, and release-process.md and test/registry-preflight.test.ts now refer to preview.5.
• The Claude plugin and marketplace are rebuilt against 2.0.0-preview.5. The coordinator is stamped with the SDK version, so leaving the plugin pinned to preview.4 would give the stamp and the pin different versions. The merge and the dispatch should happen close together: until the preview.5 packages are on npm, the plugin's npx fallback (opt-in with SQUAD_ALLOW_NPX=1) can't install the CLI.
• A new docs section, One team, teammates on different hosts, in using-squad-across-clients.md. It's backed by today's live run: Claude Code 2.1.318 and Copilot CLI 1.0.111 sharing one squad (fix(coordinator): a user's team decision reaches decisions.md in the same turn #2505).

Checks run locally

• node scripts/release/policy-gates.mjs --mode=release: all 7 gates pass (workspace-integrity, prerelease-guard, node-security-floor, publish-policy, publish-allowlist, changelog-heading, changeset-drain).
• SKIP_BUILD_BUMP=1 npm run build made no version or lockfile changes.
• npx vitest run: 412 of 412 test files pass (13,543 tests).

Held, as for preview.4: Homebrew, WinGet, latest and stable promotion. npm publishes insider as canonical, with preview as an alias.

After merge (a human runs this; agents don't dispatch releases):

VERSION=2.0.0-preview.5
SHA=$(git rev-parse origin/dev)
gh workflow run squad-release.yml --ref dev -f confirm_tag="v$VERSION" -f expected_sha="$SHA" -f npm_dist_tag=insider -f add_preview_alias=true -f publish_standalone=true -f publish_package_managers=false

🔵 Needs a closer look

Release-owner review is needed to coordinate the marketplace’s preview.5 requirements with separate npm publication, avoiding an interval where the plugin requires an unavailable CLI or bridge.
