test(KB-636): expand mission integration coverage

- Add deeper MissionStore integration tests for hierarchy integrity, rollups, reorders, and task link cleanup
- Extend mission API end-to-end coverage for feature patching, validation, and cascade scenarios
- Fix TaskStore task upsert placeholders to preserve mission slice linking fields after merge resolution
- Tidy mission CLI help text and include the published package changeset for the missions launch
