Assertoor Refactoring

Summary

Major refactoring introducing a modern React frontend with real-time updates and visual test building capabilities.

Key Changes:

• Event System: New pub/sub event bus with SSE streaming for real-time task/test state updates
• Task Lifecycle: Tasks now self-complete on success (no more stopChildOnResult). New continueOnPass option for long-running monitors
• React UI: Complete rewrite with React 18, TailwindCSS, React Query, and Zustand
• Graph Visualization: Interactive task DAG using React Flow with live status updates
• Test Builder: Drag-and-drop visual test editor with task palette, auto-generated config forms, and YAML import/export
• Spamoor Integration: Replaced pkg/wallet with spamoor library for robust transaction management
• JWT Authentication: Protected API endpoints with token-based auth

Breaking Changes

Removed	Replacement
stopChildOnResult	Tasks self-complete
expectFailure	invertResult
succeedTaskCount / failTaskCount	successThreshold / failureThreshold
failOnUndecided	Removed (fail if any child fails)
ignoreFailure	ignoreResult
