Task: Integrate bundled official Plugin device-status fix

Identity

Integrate feature commit 6bd9287c879dca93da11e17533f84e3535fc656a onto local main from its exact parent 9ed9bf4a715e300420e7a764a4cf576a6dfc4938.
Reconcile the source outcome into current state and remove only the duplicate source task record from the default-branch checkpoint.

Concurrent Task Gate: Passed after releasing the completed prior integration lock and claiming this exact root/main worktree in Integration mode.
Planning Gate: Passed after reading the source task outcome, ADR-008, current Plugin architecture/business rules, current state, and the prior scaffold landing record.
Preserve the three explicitly adopted historical task records byte-for-byte and uncommitted; do not stash, reset, clean, move, or delete them.
Preserve the accepted boundary: Project Scaffold ships in the signed client, has no device download action, and still requires server-authoritative free account acquisition before project enablement.

Cherry-picked feature source 6bd9287c879dca93da11e17533f84e3535fc656a onto local main as product commit 6d102b2 without conflict.
Removed only the duplicate source task record from the default-branch documentation checkpoint; it remains intact on the source branch and commit.
Updated current state with the accepted presentation correction and the separate production server deployment/migration requirement.
Preserved all three adopted historical task records byte-for-byte and uncommitted.

Source evidence: focused Plugin page/model 35 passed; typecheck and scoped ESLint passed; all Vite targets passed; isolated Pi timing rerun 6/6 and pressure 1/1 passed.
Source commit and landed product commit have the exact same tree 1976d2f27f239dead6d26f99131182c7c657a9db.
Root replay was not claimed because the root checkout has no installed Vitest or TypeScript executables; no dependency mutation was performed there.
Local server evidence remains separate: Project Scaffold Marketplace tests 2/2 and sole migration head 20260904_project_scaffold_0085.

Deploy the current Works Square server and migrate production through 0085 so the public catalog can authorize and expose 免费获取.
