Add FOR610 tool/workflow knowledge base and data pipeline

Build comprehensive malware analysis knowledge base from 3 sources:
- SANS FOR610 course: 120 tools, 47 labs, 15 workflows, 27 recipes
- REMnux salt-states: 340 packages parsed from GitHub
- REMnux docs: 280+ tools scraped from docs.remnux.org

Master inventory merges all sources into 447 tools with help tiers
(rich/standard/basic). Pipeline generates: tools.db (397 entries),
397 cheatsheets with multi-tool recipes, 15 workflow guides, 224
TLDR pages, and coverage reports.
