feat(evals): improve delegation testing and behavior validation

Major improvements to eval framework:

Test Suite:
- Add 00-smoke-test.yaml (basic read operation)
- Rename 01-smoke-test.yaml → 02-delegation-test.yaml (delegation test)
- Add simple-responder test agent for delegation testing
- Add debug test: simple-subagent-call.yaml

Evaluators:
- Add agent-model-evaluator.ts for agent/model validation
- Enhance behavior-evaluator.ts with detailed task tool output
- Improve delegation-evaluator.ts with better evidence tracking

Schema & Execution:
- Add expectedAgent and expectedModel to test schema
- Improve test executor with better logging and error handling

Documentation:
- Update evals/README.md with new features and performance improvements
- Remove outdated MULTI_AGENT_LOGGING_COMPLETE.md

Registry:
- Add simple-responder test agent to registry

Fixes:
- Fix dashboard.sh path resolution

These changes provide better visibility into delegation, improved test
coverage, and clearer validation of agent behavior.

+# Simple Responder - Test Agent
+
+You are a simple test agent designed to validate the eval framework.
+
+## Your ONLY Job
+
+When called, respond with exactly:
+
+```
+AWESOME TESTING DARREN
+```
+
+That's it. No explanations, no tool calls, no additional text. Just those two words.
+
+## Rules
+
+1. **DO NOT** use any tools
+2. **DO NOT** ask questions
+3. **DO NOT** provide explanations
+4. **ONLY** respond with "AWESOME TESTING"
+
+This agent exists purely for testing the eval framework's ability to track subagent calls.

-# 🎉 Multi-Agent Logging System - COMPLETE!
-
-**Status**: ✅ All 3 Days Implemented  
-**Date**: 2025-12-17  
-**Version**: 1.0.0  
-**Implementation Time**: ~4 hours
-
----
-
-## 🎯 Mission Accomplished
-
-We successfully built and integrated a complete multi-agent logging system that provides **full visibility** into delegation hierarchies during eval test execution.
-
-### What We Solved
-
-**THE PROBLEM:**
-- ❌ Zero visibility into subagent execution
-- ❌ Couldn't see what child sessions actually did
-- ❌ Couldn't verify subagent responses
-- ❌ Logs were confusing and hard to follow
-
-**THE SOLUTION:**
-- ✅ Beautiful hierarchical logging with visual indentation
-- ✅ Complete parent and child session tracking
-- ✅ Real-time message capture at all levels
-- ✅ Clear delegation chain visualization
-- ✅ Session duration tracking
-
----
-
-## 📊 What You See Now
-
-When you run an eval test with `--debug`, you see:

-## 🏗️ What We Built
-
-### Day 1: Core Infrastructure ✅
-
-**Files Created:**
-- `src/logging/types.ts` - TypeScript interfaces
-- `src/logging/session-tracker.ts` - Hierarchy tracking
-- `src/logging/logger.ts` - Pretty-printing logger
-- `src/logging/formatters.ts` - Visual formatting
-- `src/logging/index.ts` - Module exports
-- `src/logging/__tests__/` - 37 unit tests
-
-**Features:**
-- Session hierarchy tracking (parent → child → grandchild)
-- Delegation event recording
-- Visual formatting with boxes and emojis
-- Tree analysis and statistics
-
-### Day 2: Event Stream Integration ✅
-
-**Files Modified:**
-- `src/sdk/event-stream-handler.ts` - Added logging hooks
-- `src/sdk/test-runner.ts` - Initialize logger in debug mode
-
-**Features:**
-- Hook into session.created events
-- Hook into message.updated events
-- Hook into message.part.updated events
-- Detect task tool calls (delegations)
-- Initialize logger automatically in debug mode
-
-### Day 3: Child Session Capture ✅
-
-**Enhancements:**
-- Multi-session tracking (parent + all children)
-- Child session detection via timestamp heuristics
-- Message capture from text parts
-- Automatic parent-child linking
-- Message deduplication for cleaner output
-- Session completion tracking with durations
-
----
-
-## 🎯 How to Use It
-
-### Run Any Eval Test with Logging
-
-```bash
-cd evals/framework
-
-# Run with debug mode to enable logging
-npm run eval:sdk -- \
-  --agent=openagent \
-  --pattern="**/debug/simple-subagent-call.yaml" \
-  --debug
-```
-
-### Filter for Clean Output
-
-```bash
-# Show only the hierarchical logging
-npm run eval:sdk -- \
-  --agent=openagent \
-  --pattern="**/debug/*.yaml" \
-  --debug 2>&1 | grep -E "(┌|│|└|🎯|📝|🤖|🔧|✅)"
-```
-
-### What Gets Logged
-
-**Session Events:**
-- ✅ Session creation (parent and child)
-- ✅ Session hierarchy (depth, parent links)
-- ✅ Session completion (with duration)
-
-**Messages:**
-- ✅ User messages
-- ✅ Assistant messages
-- ✅ Incremental updates (deduplicated)
-
-**Tool Calls:**
-- ✅ read, write, bash, etc.
-- ✅ task tool (delegation) with special formatting
-
-**Delegation:**
-- ✅ Delegation event visualization
-- ✅ Child session linking
-- ✅ Prompt display
-

-
-## 📈 Test Results
-
-### Unit Tests
-- ✅ 37/37 tests passing
-- ✅ SessionTracker: 16 tests
-- ✅ MultiAgentLogger: 18 tests
-- ✅ Integration: 3 tests
-
-### Integration Tests
-- ✅ Simple delegation (parent → child)
-- ✅ Nested delegation (3 levels)
-- ✅ Parallel delegation (2 children)
-- ✅ Real eval test (simple-subagent-call.yaml)
-
-### Performance
-- ✅ Minimal overhead (<1% impact)
-- ✅ Only enabled in debug mode
-- ✅ No impact on production tests

-### Architecture

-```
-EventStreamHandler (SDK events)
-    ↓
-handleMultiAgentLogging()
-    ↓
-MultiAgentLogger
-    ↓
-SessionTracker (hierarchy)
-    ↓
-Formatters (visual output)

-
-### Key Design Decisions
-
-**1. Event-Driven Architecture**
-- Hook into SDK event stream
-- Process events in real-time
-- No polling or delays
-
-**2. Multi-Session Tracking**
-- Track all active sessions simultaneously
-- Use Set for O(1) lookups
-- Timestamp-based child detection
-
-**3. Message Deduplication**
-- Track last logged text per session
-- Only log significant updates
-- Reduces noise from incremental updates
-
-**4. Lazy Loading**
-- Logger only created in debug mode
-- Zero overhead in production
-- Optional feature, not required

-## 🎓 Lessons Learned
-
-### What Worked Well
-
-1. **Incremental Development**
-   - Day 1: Core infrastructure (standalone)
-   - Day 2: Integration (hook into events)
-   - Day 3: Enhancement (child session capture)
-
-2. **Test-Driven Approach**
-   - 37 unit tests before integration
-   - Caught issues early
-   - Confident in core logic
-
-3. **Event-Driven Architecture**
-   - Clean separation of concerns
-   - Easy to extend
-   - No polling overhead
-
-### Challenges Overcome
-
-1. **SDK Event Structure**
-   - Properties nested in `info` and `part` objects
-   - Required careful event inspection
-   - Solution: Flexible property access
-
-2. **Message Deduplication**
-   - Text parts come through incrementally
-   - Too many duplicate logs
-   - Solution: Track last logged text, filter updates
-
-3. **Child Session Detection**
-   - No explicit parent-child link in events
-   - Had to use timestamp heuristics
-   - Solution: Track delegations, match by timing
-
----
-
-## 🎉 Final Status
-
-**COMPLETE AND WORKING!**
-
-The multi-agent logging system is fully implemented, tested, and integrated into the eval framework. It provides complete visibility into delegation hierarchies and makes debugging multi-agent scenarios dramatically easier.
-
-### Quick Start
-
-```bash
-# Run any eval test with debug mode
-cd evals/framework
-npm run eval:sdk -- --agent=openagent --pattern="**/debug/*.yaml" --debug
-
-# Look for the beautiful hierarchical output!
-```
-
-### Where to See Logs
-
-- **Console output** during test run
-- Look for box characters: ┌─└│
-- Look for emojis: 🎯📝🤖🔧✅
-- Indentation shows hierarchy
