Add security review references for secret detection patterns, vulnerability categories, and vulnerable packages

- Created `secret-patterns.md` for high-confidence secret patterns and entropy-based detection.
- Added `vuln-categories.md` detailing various vulnerability types and detection guidance.
- Introduced `vulnerable-packages.md` listing known vulnerable packages across multiple ecosystems.
- Implemented skills for suggesting relevant GitHub Copilot agents, instructions, and skills based on repository context.
- Each skill includes processes for fetching, comparing, and validating against existing local resources.

+# Context Map
+
+Before implementing any changes, analyze the codebase and create a context map.
+
+## Task
+
+{{task_description}}
+
+## Instructions
+
+1. Search the codebase for files related to this task
+2. Identify direct dependencies (imports/exports)
+3. Find related tests
+4. Look for similar patterns in existing code
+
+## Output Format
+
+```markdown
+## Context Map
+
+### Files to Modify
+| File | Purpose | Changes Needed |
+|------|---------|----------------|
+| path/to/file | description | what changes |
+
+### Dependencies (may need updates)
+| File | Relationship |
+|------|--------------|
+| path/to/dep | imports X from modified file |
+
+### Test Files
+| Test | Coverage |
+|------|----------|
+| path/to/test | tests affected functionality |
+
+### Reference Patterns
+| File | Pattern |
+|------|---------|
+| path/to/similar | example to follow |
+
+### Risk Assessment
+- [ ] Breaking changes to public API
+- [ ] Database migrations needed
+- [ ] Configuration changes required
+```
+
+Do not proceed with implementation until this map is reviewed.
