chore: move ccw-skill-hub to standalone repository

Migrated ccw-skill-hub to D:/ccw-skill-hub as independent git project.
Removed nested git repos (ccw/frontend/ccw-skill-hub, skill-hub-repo, skill-hub-temp).

+# Review Dimensions (4-Dimension System)
+
+## Security (SEC)
+
+Vulnerabilities, attack surfaces, and data protection issues.
+
+**Categories**: injection, authentication, authorization, data-exposure, encryption, input-validation, access-control
+
+**Tool Support**: Semgrep (`--config auto`), npm audit, tsc strict mode
+**LLM Focus**: Business logic vulnerabilities, privilege escalation paths, sensitive data flows
+
+**Severity Mapping**:
+- Critical: RCE, SQL injection, auth bypass, data breach
+- High: XSS, CSRF, insecure deserialization, weak crypto
+- Medium: Missing input validation, overly permissive CORS
+- Low: Informational headers, minor config issues
+
+---
+
+## Correctness (COR)
+
+Bugs, logic errors, and type safety issues.
+
+**Categories**: bug, error-handling, edge-case, type-safety, race-condition, null-reference
+
+**Tool Support**: tsc `--noEmit`, ESLint error-level rules
+**LLM Focus**: Logic errors, unhandled exception paths, state management bugs, race conditions
+
+**Severity Mapping**:
+- Critical: Data corruption, crash in production path
+- High: Incorrect business logic, unhandled error in common path
+- Medium: Edge case not handled, missing null check
+- Low: Minor type inconsistency, unused variable
+
+---
+
+## Performance (PRF)
+
+Inefficiencies, resource waste, and scalability issues.
+
+**Categories**: n-plus-one, memory-leak, blocking-operation, complexity, resource-usage, caching
+
+**Tool Support**: None (LLM-only dimension)
+**LLM Focus**: Algorithm complexity, N+1 queries, unnecessary sync operations, memory leaks, missing caching
+
+**Severity Mapping**:
+- Critical: Memory leak in long-running process, O(n³) on user data
+- High: N+1 query in hot path, blocking I/O in async context
+- Medium: Suboptimal algorithm, missing obvious cache
+- Low: Minor inefficiency, premature optimization opportunity
+
+---
+
+## Maintainability (MNT)
+
+Code quality, readability, and structural health.
+
+**Categories**: code-smell, naming, complexity, duplication, dead-code, pattern-violation, coupling
+
+**Tool Support**: ESLint warning-level rules, complexity metrics
+**LLM Focus**: Architectural coupling, abstraction leaks, project convention violations
+
+**Severity Mapping**:
+- High: God class, circular dependency, copy-paste across modules
+- Medium: Long method, magic numbers, unclear naming
+- Low: Minor style inconsistency, commented-out code
+- Info: Pattern observation, refactoring suggestion
+

+
+## Why 4 Dimensions (Not 7)
+
+The original review-cycle used 7 dimensions with significant overlap:
+
+| Original | Problem | Merged Into |
+|----------|---------|-------------|
+| Quality | Overlaps Maintainability + Best-Practices | **Maintainability** |
+| Best-Practices | Overlaps Quality + Maintainability | **Maintainability** |
+| Architecture | Overlaps Maintainability (coupling/layering) | **Maintainability** (structure) + **Security** (security architecture) |
+| Action-Items | Not a dimension — it's a report format | Standard field on every finding |
+
+4 dimensions = clear ownership, no overlap, each maps to distinct tooling.
