Add complete QLM (Quantum Language Model) implementation

This commit introduces the QLM system - a stateful semantic layer for
tracking HI (Human Intelligence), AI (Agent Intelligence), and QI
(Quantum/Emergent Intelligence) in BlackRoad OS.

Core Features:
- HI/AI/QI intelligence layer modeling
- Event-driven state management
- QI emergence detection (agent self-correction, feedback loops, etc.)
- HI-AI alignment scoring
- Operator-facing query interface
- Reality ingestion (git, CI, agent logs)

Components Added:
- qlm_lab/models.py: Core data models (Actor, QLMEvent, QIEmergence, etc.)
- qlm_lab/state.py: State management and transition tracking
- qlm_lab/api.py: Public QLMInterface API
- qlm_lab/ingestion/: Git, CI, and agent log connectors
- qlm_lab/experiments/: Alignment and emergence validation
- qlm_lab/visualization.py: Timeline, actor graph, alignment plots
- qlm_lab/demo.py: Interactive demo script
- tests/test_qlm_core.py: Comprehensive test suite
- docs/QLM.md: Complete documentation (concepts, API, integration)

Usage:
  from qlm_lab.api import QLMInterface

  qlm = QLMInterface()
  qlm.record_operator_intent("Build feature X")
  qlm.record_agent_execution("agent-1", "Implement X", "task-1")
  summary = qlm.get_summary(days=7)

Run:
  python -m qlm_lab.demo
  python -m qlm_lab.experiments.alignment_detection
  pytest tests/test_qlm_core.py -v

Integrates with:
- cognitive/intent_graph.py (intent tracking)
- cognitive/agent_coordination.py (multi-agent coordination)
- operator_engine/scheduler.py (background analysis)

Next steps: Integrate with FastAPI backend, add Prism Console UI,
implement Lucidia language runtime.
