Wizard: Add 'Auto-run all phases' checkbox

[pedramamini]

Summary

The new agent wizard currently auto-starts only the first phase document after launch. Add a checkbox to the Phase Review screen that lets users opt into auto-running all generated phases sequentially.

Current Behavior

In useWizardHandlers.ts (~line 1204), the wizard finds the first document with tasks and builds a single-entry BatchRunConfig:

const firstDocWithTasks = generatedDocuments.find((doc) => doc.taskCount > 0);
// ...
documents: [{ id: generateId(), filename: firstDocWithTasks.filename.replace(/\.md$/, ''), ... }],
loopEnabled: false,

Only Phase 01 auto-runs. The user must manually open the Batch Runner to continue with subsequent phases.

Proposed Behavior

• Add a checkbox to PhaseReviewScreen.tsx (below the document editor, near the launch buttons): "Auto-run all phases" — default off.
• When checked, handleWizardLaunchSession should populate BatchRunConfig.documents with all generated documents that have taskCount > 0, not just the first.
• The batch runner infrastructure (useBatchProcessor, useBatchHandlers) already supports multi-document sequential runs — no changes needed there.

Key Files

File	Change
src/renderer/components/Wizard/screens/PhaseReviewScreen.tsx	Add checkbox UI + state
src/renderer/hooks/wizard/useWizardHandlers.ts	Conditionally build single-doc vs all-docs BatchRunConfig
src/renderer/components/Wizard/WizardContext.tsx	Thread autoRunAll flag through wizard state (if needed)

Notes

• Default off is intentional — running all phases unattended is a power-user workflow. Most users want to review results between phases.
• The existing BatchRunConfig shape already supports multiple documents, so this is mostly a wiring change.
