Release v1.7 — i18n + Rename Cognik + Purity Audit · int2t05/Cognik

Highlights

Frontend zh/en switch via next-intl (cookie-based, no [locale] URL prefix) — locale: cookie → Accept-Language → fallback Chinese; SSR renders correct locale with no hydration flash
GitHub display surface English-first: bilingual README & CONTRIBUTING with cross-links, bilingual Issue templates
Full string extraction across all portal/admin pages and shared components → messages/{zh,en}.json
CONTRIBUTING accepts Chinese or English commit messages; code comments stay Chinese

Eliminated naming conflict with IBM Cognos Analytics (search visibility was severely diluted)
Cognik = Cognition + -ik (tech suffix) — GitHub has no same-name project, low trademark risk
Full rename: Go module path, env prefix (COGNOS_ → COGNIK_), brand name across 277 files
GitHub repo renamed (old URL auto-redirects), SEO-optimized description & README

Dead link fix: docs/design/DESIGN.md (directory removed, link not synced)
Embedding dimension unified across README/PRD/TECH (Qwen3@1024 / DashScope@1536, configurable)
admin-ops-flow.md: 5 doc/impl gaps fixed (field names, trend structure, config keys, message types)
knowledge-publish-flow.md: removed Review audit-log hallucination, added Disable audit+BM25 steps, fixed stale line numbers
4 cross-directory dead links fixed (knowledge/ ↔ chat/)
Dead config field removed (COGNOS_AI_CONFIDENCE_THRESHOLD → _LOW/_HIGH)

Removed orphan shared/handler/common.go (functions inlined per-domain; domain-first layering)
.gitignore covers rerank model artifacts
Test signature fix for AutoMigrate vector-dimension parameter
