[codex] re-anchor org docs around AevumGuard

[raylee-hawkins]

Summary

Re-anchors the HawkinsOperations org documentation around AevumGuard as the main ProofOps product/front-door repo.

• Replaces standalone Product 001: Claim Firewall framing with Product: AevumGuard.
• Describes Claim Firewall only as the first internal Claim Authority capability inside AevumGuard.
• Adds the seven-repo authority model and explicit no-eighth-repo rule.
• Preserves existing truth boundaries and blocked runtime/signal/public-safe claims.

Proof ceiling

Public routing clarity only. No proof promotion.

Validation

• git status --short
• python scripts/verify-command-center-invariants.py
• git diff --check HEAD~1..HEAD
