fix: P1 Advanced Mode chain-of-thought interpretability (#106)

Problem: Advanced orchestrator exposed raw internal framework events
from agent-framework-core to users:
- `Manager (task_ledger): We are working to address...` (truncated)
- `Manager (instruction): Conduct targeted searches...` (truncated)
- All mapped to type="judging" regardless of actual purpose

Solution:
1. Filter internal events: `task_ledger` and `instruction` now hidden
2. Transform: `user_task` → type="progress" with friendly message
3. Smart truncation: Cut at sentence/word boundaries, not mid-word

Tests: tests/unit/orchestrators/test_advanced_events.py (4 tests)

Closes #106

-These are framework-internal bookkeeping truncated at 200 chars, making them uninterpretable.
-
 **Root Cause:** `_process_event()` in `advanced.py` doesn't filter or transform `MagenticOrchestratorMessageEvent` events from `agent-framework-core`.
 
-**Solution Options:**
-1. Filter internal events (`user_task`, `task_ledger`, `instruction`)
-2. Transform to user-friendly messages ("Manager assigning search task...")
-3. Add verbose mode for debugging

 3. Shown with misleading "JUDGING" event type
 4. Not meaningful to end users
 
+## Resolution
+
+Implemented "Smart Filter + Transform" logic in `src/orchestrators/advanced.py`:
+
+1. **Filtered**: `task_ledger` and `instruction` events are now hidden.
+2. **Transformed**: `user_task` events are mapped to `type="progress"` with a friendly "Manager assigning research task..." message.
+3. **Smart Truncation**: Text is now truncated at sentence boundaries or word boundaries, preventing mid-word cuts.
+
+Verified with new unit tests in `tests/unit/orchestrators/test_advanced_events.py`.
