quarantine: scrub tailnet ref, add license, ship lab/ repro kit, refresh README for cohort

- untrack CLAUDE.md (tailnet leak) + stale HANDOFF.md; keep local via .gitignore
- add source-available LICENSE (attribution on fork, royalty on commercial use)
- add lab/ reproduction kit (fake-cred LIVE-VM/mock rotation POCs) + lab/README
- rewrite README to current status (22 drivers, 8 LIVE-VM/14 MOCK-ONLY/0 LIVE-REAL,
  247 tests) and carry the credential-handling safety rules
