feat: Fix review issues and integrate ASTRAL, PULSAR, AURORA product suite

Framework fixes:
- antifragile-manifest.md: Correct AI Sovereignty pillar (data residency/audit rights framing); add consultant note
- executive-summary.md: Same AI sovereignty correction; add EU Regulatory Context (NIS2, DORA, GDPR)
- README.md: Add Brownhat brand explanation; expand Standards Alignment with NIS2/DORA/GDPR
- core/about-cqre.md: Prominent TEMPLATE WARNING banner to prevent accidental sharing
- index.md: Add CQRE Product Suite; renumber consultant nav 1-26 consistently

New: playbooks/cqre-product-suite.md - ASTRAL/PULSAR/AURORA product reference with antifragile pillar alignment, regulatory mapping, deployment prerequisites, and objection handling

Updated: sovereign-tool-stack.md - ASTRAL updated to GitHub product spec; AOC replaced with PULSAR; AURORA section added
