ultraplanlisted

# Ultraplan Turn an agreed design into a step-by-step plan that another contributor could execute without context. Cover: - Scope and the exact files to create/modify (use real paths). - The IPC contract changes: new channels in `src/shared/ipc.ts` (type + runtime allowlist), the zod-validated handler, and the service it calls. - Data flow renderer ↔ main, and any store changes. - Security: filesystem jail usage, `gitInvoke` for git, `secretMask` for any config display. - Tests to add in `tests/unit` (pure logic: parsers, mappers, validators). - The order to build in, and acceptance criteria. Stop and get approval before implementing. Keep `npm run typecheck && npm test && npm run build` green at every step.
