Timmy b32d316023 feat(#10): knowledge file format schema + example knowledge files
- SCHEMA.md: full specification for index.json and YAML knowledge files
- knowledge/global/pitfalls.yaml: 8 cross-repo pitfalls
- knowledge/global/tool-quirks.yaml: 7 environment quirk facts
- knowledge/repos/hermes-agent.yaml: 8 per-repo pitfalls (cron, paths, SSH)
- knowledge/repos/the-nexus.yaml: 6 per-repo pitfalls (merge, server, deploy)
- scripts/validate_knowledge.py: schema validator (29 facts, all passing)
- knowledge/index.json: populated with 29 seed facts from real fleet data

Design decisions:
- YAML for humans, index.json for machines
- ID format: domain:category:sequence for dedup and linking
- 5 categories: fact, pitfall, pattern, tool-quirk, question
- Confidence 0.0-1.0 with defined ranges
- Related facts by ID for graph traversal
- Tags for searchability
- Source count + dates for decay/expiry

Acceptance criteria:
- [x] Directory structure created
- [x] Schema documented (SCHEMA.md)
- [x] index.json with real facts (29 total)
- [x] Example knowledge files for 2 repos (hermes-agent, the-nexus)
- [x] Validation script passes
