feat: Implement Agentic Architecture for robust session workflows

Phase 1 - Session Bootstrap:
- Add .claude/ATOMIZER_CONTEXT.md as single entry point for new sessions
- Add study state detection and task routing

Phase 2 - Code Deduplication:
- Add optimization_engine/base_runner.py (ConfigDrivenRunner)
- Add optimization_engine/generic_surrogate.py (ConfigDrivenSurrogate)
- Add optimization_engine/study_state.py for study detection
- Add optimization_engine/templates/ with registry and templates
- Studies now require ~50 lines instead of ~300

Phase 3 - Skill Consolidation:
- Add YAML frontmatter metadata to all skills (versioning, dependencies)
- Consolidate create-study.md into core/study-creation-core.md
- Update 00_BOOTSTRAP.md, 01_CHEATSHEET.md, 02_CONTEXT_LOADER.md

Phase 4 - Self-Expanding Knowledge:
- Add optimization_engine/auto_doc.py for auto-generating documentation
- Generate docs/generated/EXTRACTORS.md (27 extractors documented)
- Generate docs/generated/TEMPLATES.md (6 templates)
- Generate docs/generated/EXTRACTOR_CHEATSHEET.md

Phase 5 - Subagent Implementation:
- Add .claude/commands/study-builder.md (create studies)
- Add .claude/commands/nx-expert.md (NX Open API)
- Add .claude/commands/protocol-auditor.md (config validation)
- Add .claude/commands/results-analyzer.md (results analysis)
