Complete remaining medium/low issues: performance, CLI, types, CI, tests

Performance:
- Batch readiness computation (~200 queries → ~6 per page)
- Batch draft lookup in author network (N+1 → single query)
- File-based similarity matrix cache (.npy + metadata sidecar)
- 5-minute TTL embedding cache for search queries

CLI quality:
- Add pass_cfg_db decorator, convert ~30 commands to shared config/db lifecycle
- Add --dry-run to analyze, embed, embed-ideas, ideas, gaps commands
- Move 15+ in-function imports to top of data.py

Types & documentation:
- Add 16 TypedDicts to data.py, annotate 12 function return types
- Add ethics section to Post 06 (premature standardization, power asymmetry)
- Add EU AI Act Article 43 conformity mapping to Post 06
- Add NIS2 and CRA references to Post 04

CI & testing:
- Add GitHub Actions CI workflow (Python 3.11+3.12, ruff, pytest)
- Add API documentation for all 20 endpoints (data/reports/api-docs.md)
- Add 41 new tests (test_analyzer.py, test_search.py) — 64 total pass
