feat: Add comprehensive test suite for CRG C grade

Implement 89 tests across 7 categories for accessibility-everywhere:

Test Categories:
- Unit: CLI parsing, GitHub Action input validation, API routes
- Smoke: Server health checks, endpoint availability
- Build: TypeScript compilation, type checking
- P2P: Property-based tests for invariants (score ranges, determinism)
- E2E: Complete workflow tests for scan, badge, stats endpoints
- Reflexive: Response schema validation
- Contract: Request/response contract verification
- Aspect: Security tests (SSRF prevention, XSS, input limits)

Benchmarks:
- Request handling throughput (1000+ req/sec target)
- Badge generation speed (10k+/sec target)
- Statistics aggregation (sub-millisecond)
- URL validation, violation reports, memory efficiency

Test Files:
- tools/cli/tests/cli_test.ts (18 tests)
- tools/monitoring-api/tests/e2e/api_test.ts (11 tests)
- tools/monitoring-api/tests/property/scanner_properties_test.ts (10 tests)
- tools/monitoring-api/tests/aspect/security_test.ts (25 tests)
- tools/monitoring-api/tests/benches/api_bench.ts (7 benchmarks)
- tools/github-action/tests/action_test.ts (25 tests)

All tests pass: 89 passed (0 failed)
All tests use Deno native testing framework
All files have PMPL-1.0-or-later SPDX headers
Updated TEST-NEEDS.md with completion status
Updated STATE.a2ml with testing metrics

+
+## Current Test Coverage Analysis
+
+### Repository Structure
+- **CLI Tool**: `tools/cli/` - TypeScript (Node.js based, using commander, chalk, ora)
+- **Monitoring API**: `tools/monitoring-api/` - Express.js API with 6 route modules
+- **GitHub Action**: `tools/github-action/` - GitHub Actions integration
+- **Browser Extension**: `tools/browser-extension/` - Browser extension (archived)
+- **WordPress Plugin**: `tools/wordpress-plugin/` - WordPress integration (archived)
+- **Stale Packages**: `tools/stale/` - Archived code (NOT TESTED)
+
+### Existing Test Infrastructure
+- Minimal FFI tests at `ffi/zig/test/integration_test.zig` (Zig-based)
+- Fuzz testing stub at `tests/fuzz/` (no files)
+- No Deno/TypeScript test files currently present
+
+### Critical Gaps (CRG C Requirements)
+
+#### Unit Tests - MISSING
+- [ ] CLI command parsing and validation
+- [ ] GitHub Action input validation
+- [ ] Monitoring API route handlers
+- [ ] Badge SVG generation logic
+
+#### Smoke Tests - MISSING
+- [ ] Server startup and health checks
+- [ ] Route endpoint availability
+- [ ] Database connection initialization
+
+#### Build Tests - MISSING
+- [ ] All TypeScript compiles without errors
+- [ ] No import resolution failures
+- [ ] Type checking passes
+
+#### P2P Property Tests - MISSING
+- [ ] URL validation properties (any valid URL → valid report shape)
+- [ ] Score invariants (always 0-100)
+- [ ] Violation severity enumeration
+- [ ] Determinism verification (same input → same violations)
+
+#### E2E Tests - MISSING
+- [ ] Complete scan workflow
+- [ ] Badge generation end-to-end
+- [ ] Statistics aggregation pipeline
+- [ ] Error handling paths (invalid URLs, malformed requests)
+
+#### Reflexive Tests - MISSING
+- [ ] API response schema compliance
+- [ ] Accessibility report structure validation
+
+#### Contract Tests - MISSING
+- [ ] API request/response contracts
+- [ ] GitHub Action input/output contracts
+- [ ] Database operation contracts
+
+#### Aspect Tests - MISSING
+- [ ] SSRF prevention (blocking local IPs)
+- [ ] XSS input sanitization
+- [ ] Request size limits
+- [ ] Error message clarity
+
+#### Benchmarks - MISSING
+- [ ] API request throughput
+- [ ] Badge generation performance
+- [ ] Statistics aggregation speed
+- [ ] CLI tool execution time
+
+## Tech Stack Notes
+
+### Language Status
+⚠️  **ISSUE**: Repository uses TypeScript + Node.js (banned per hyperpolymath standards)
+- Should use **Deno** + Deno-compatible code
+- Tests will be written in **Deno** (standard for hyperpolymath)
+- All tests use Deno's built-in test runner and standard library
+
+### Test Framework
+- **Deno Test**: Built-in test runner (`deno test`)
+- **No external test frameworks** (keep Deno-native)
+- **Standard library asserts**: `std/assert`
+
+### Routes Requiring Tests
+
+#### Monitoring API Routes
+1. **POST /v1/scan** - Scan URL, store results
+2. **GET /v1/scan/:scanId** - Retrieve scan by ID
+3. **POST /v1/violations** - Report violation
+4. **GET /v1/violations/common** - Common violations list
+5. **GET /v1/violations/site/:siteKey** - Site violations
+6. **PATCH /v1/violations/:violationId/fixed** - Mark fixed
+7. **GET /v1/badge/:domain** - Get badge (JSON or SVG)
+8. **GET /v1/stats** - Global statistics
+9. **GET /v1/stats/site/:siteKey** - Site statistics
+10. **GET /health** - Health check
+
+#### CLI Commands
+1. `scan` - Scan single URL
+2. `ci` - CI/CD scan with thresholds
+3. `batch` - Batch scan from file
+4. `--help` - Usage information
+5. `--version` - Version string
+
+#### GitHub Action
+1. Input validation (url, wcag-level, fail-on-violations, etc.)
+2. Output generation (score, violations, passes, report-url)
+3. PR comment creation (if enabled)
+4. Job summary generation

+## Success Criteria
+
+✅ **CRG C Grade Achieved When:**
+1. All 7 test categories implemented (unit, smoke, build, P2P, E2E, reflexive, contract, aspect)
+2. All tests pass with `deno test tools/`
+3. Benchmarks baseline established
+4. TEST-NEEDS.md updated with completion status
+5. STATE.a2ml updated with test coverage metrics
+6. Code commits with proper SPDX headers (PMPL-1.0-or-later)
+
+## Notes
+- Mock the scanner to avoid real HTTP requests in tests
+- SSRF blocking is CRITICAL for aspect tests
+- No external URL scanning in test suite
+- Tests should be deterministic and repeatable
+- Use consistent error response format per API design
