Add Escalation UX

Status

Future work item. Kept after first-run setup, handoff output, guide cleanup, and schema-led initiatives because escalation should build on a sane onboarding path.

Goal

Let users start locally and upgrade into a coordinated initiative only when the work actually needs shared context.

Ship

• Explore/propose guidance that starts in the current repo by default.
• Recommendation triggers when work spans multiple owned areas.
• Carry-forward behavior for current change name, product goal, notes, inferred areas, and relevant questions.
• Prompts grounded in concrete affected areas instead of abstract storage models.

Done When

• Coordinated planning feels like a continuation of local planning, not a workflow restart.
