feat(framework): P1+P2 — public sanitization + blocking CI gate

Adds tools/quality/scripts/verify-sanitized.sh (two-class, self-tested) wired
blocking in .woodpecker/ci.yml; sanitizes operator identity from the public
framework package so the gate is green.

- purge jarvis/jason/woltje/PDA across 26 files -> generic
- delete jarvis-loop.json overlay; add neutral examples/{personas,overlays}
- relocate maintainer AUDIT to docs/audits/; delete 2 jarvis-brain rule blocks
- neutralize SOUL persona; strip "(Policy: Jason ...)" keeping universal rule
- test fixtures jason.woltje -> ci-bot (both git tests pass)

Deferred (tracked): private third-party host (uscllc) genericization.

Refs #542, closes #571
