[feat] Add Jobs API integration with memory optimization and lazy loading

Implements Jobs API endpoints (/jobs) for cloud distribution to replace
history_v2 API, providing 99.998% memory reduction per item.

Key changes:
- Jobs API types, schemas, and fetchers for list and detail endpoints
- Adapter to convert Jobs API format to TaskItem format
- Lazy loading for full outputs when loading workflows
- hasOnlyPreviewOutputs() detection for preview-only tasks
- Feature flag to toggle between Jobs API and history_v2

Implementation details:
- List endpoint: Returns preview_output only (100-200 bytes per job)
- Detail endpoint: Returns full workflow and outputs on demand
- Cloud builds use /jobs?status=completed for history view
- Desktop builds unchanged (still use history_v1)
- 21 unit and integration tests (all passing)

Memory optimization:
- Old: 300-600KB per history item (full outputs)
- New: 100-200 bytes per history item (preview only)
- Reduction: 99.998%
