feat(FN-813): add project-aware ntfy deep links

- Thread real project context (projectName, projectId) into ntfy notification deep links
- Dashboard deep-link URL now honors project context with /project/:name/task/:id pattern
- Update App.tsx routing to handle project-scoped deep link navigation
- Add project info to NtfyNotifier types and wire through notification payload
- Add changeset for published @gsxdsm/fusion package
- Add tests for notifier project context and dashboard routing
