Task 01: Disable same-version approval

Acceptance

• A resolved preview with identical non-empty current and target versions shows the version once with Up to date, omits the arrow transition, keeps Approve update disabled, and sends no update POST.
• Differing-version approval and failed-job retry remain enabled.
• Desktop and mobile use the same predicate, and the public Agents guide explains the unavailable approval state.
• A stale preview cannot invoke a package command after the backend resolves that the runtime is already up to date.

TDD sequence

1. Add the equal-version desktop and mobile Playwright scenarios and run each focused test to confirm it fails because the UI shows an arrow transition and the confirmation button is enabled.
2. Render one version plus Up to date, then tighten canApproveUpdate with the minimal target-presence and inequality checks.
3. Run both runtime-update spec files to prove the new regression and existing enabled paths.
4. Update and validate the public documentation.
5. Revalidate the current runtime version in the backend before executing a package command and cover the no-op job path with a Go unit test.

Verification

• From apps/ in a fresh worktree, install dependencies: pnpm install --frozen-lockfile
• Desktop E2E: pnpm --filter @kandev/web e2e:run --host tests/settings/agent-runtime-update.spec.ts
• Mobile E2E: pnpm --filter @kandev/web e2e:run --host tests/settings/mobile-agent-runtime-update.spec.ts -- --project=mobile-chrome
• Frontend typecheck: pnpm --filter @kandev/web run typecheck
• Frontend unit tests: pnpm --filter @kandev/web test -- --run lib/agent-runtime-update.test.ts
• Backend unit test: cd ../apps/backend && go test -run TestAgentUpdateJobSkipsCommandWhenRuntimeIsAlreadyUpToDate ./internal/agent/settings/controller
• Public docs: node --test scripts/validate-public-docs.test.mjs && node scripts/validate-public-docs.mjs

Dependencies

None.

Parallelism

Sequential. The E2E scenarios depend on the same shared component change and the task is one focused behavior slice.

Inputs

• Equal-version behavior in docs/specs/agents/requirements/runtime-updates.md
• Shared body presentation and footer state in apps/web/components/settings/agent-runtime-update-control.tsx
• Existing desktop and mobile runtime-update fixtures and scenarios
• Mobile parity contract in plan.md

Risks

• Preserve failed-job retries when preview versions differ.
• Do not disable the card's update icon before a fresh preview has resolved.
