Address review: register metadata engine, coverage wiring, virtual seqr fix, Xcelium wrapper, generic RAL access

Fix None access in dashboard: reg.access can be None

Fix dashboard address format: coerce reg.address to int for 02X

Phase 3: IP-XACT, CI/CD, VCS/Questa wrappers, rich dashboard

Fix: SequenceDef unhashable type error — use attr access instead of dict indexing

Phase 3: Compile correctness + RAL consistency + test mapping + quality scoring + auto-fix suggestions

Fix: initialize sim_result before use in HTML report

Fix: add missing 'import json' in pipeline.py

Fix: add missing 'import os' in pipeline.py

Phase 2: AI quality scoring, sequence library, virtual sequences, coverage crosses, scoreboard integration

Add cross-file validator+spec coverage score; fix stray brace+hardcoded widths in sequence template; enhance sequence_item

Phase 1: spec-driven templates + SV checker + quality score + ZIP export

ML model improvements: coverage predictor ensemble, coverage-driven hybrid generation, coverage RL reward shaping, pipeline integration

feat: Advanced ML V2 Model with Reinforcement Learning

feat: Add actual AI/ML capabilities with LLM, semantic embeddings, and reinforcement learning

feat: Add enhanced ML model with retrieval-augmented generation

Initial commit: UVM testbench generator with coverage-driven auto-training
