refactor(app): replace 4 component test slop files with pure module extractions (#724)

Delete message-input.test.tsx, left-sidebar.test.tsx, agent-stream-view.test.tsx, and agent-panel.test.tsx — all heavy vi.mock + JSDOM + toHaveBeenCalledWith slop. Coverage preserved by extracting the testable derivations: - agent-stream-view-data.ts: isSameAssistantBlockGroup, getAssistantBlockSpacing, resolveInlineWorkingIndicatorItemId — 14 pure unit tests, zero mocks - message-input-state.ts: computeCanStartDictation (dictation readiness gate) — 7 pure unit tests, zero mocks Remaining behaviors confirmed covered by existing E2E: - left-sidebar subscription-while-hidden → sidebar-workspace.spec.ts - agent-panel render isolation + archived agent store hygiene → archive-tab.spec.ts - message-input attachment menu / submit icon → workspace-setup-streaming.spec.ts
