chore: Add Semgrep ignore file and CI job status documentation

This commit introduces a Semgrep ignore file to suppress false positives and low-risk findings, particularly for controlled inputs in database scripts and development configurations. Additionally, a new CI Job Status Configuration document is added to clarify which CI jobs should fail on errors and which are informational, enhancing the overall CI/CD process documentation.

+# CI Job Status Configuration
+
+This document explains which CI jobs should fail on errors and which are informational.
+
+## Jobs That Should FAIL on Errors ✅
+
+These jobs will show a **red X** if they encounter errors:
+
+### 1. **lint-and-type-check**
+- ✅ ESLint (admin-frontend) - **FAILS on lint errors**
+- ✅ Type check (viewer-frontend) - **FAILS on type errors**
+- ⚠️ npm audit - **Informational only** (continue-on-error: true)
+
+### 2. **python-lint**
+- ✅ Python syntax check - **FAILS on syntax errors**
+- ✅ Flake8 - **FAILS on style/quality errors**
+
+### 3. **test-backend**
+- ✅ pytest - **FAILS on test failures**
+- ⚠️ pip-audit - **Informational only** (continue-on-error: true)
+
+### 4. **build**
+- ✅ Backend validation (imports/structure) - **FAILS on import errors**
+- ✅ npm ci (dependencies) - **FAILS on dependency install errors**
+- ✅ npm run build (admin-frontend) - **FAILS on build errors**
+- ✅ npm run build (viewer-frontend) - **FAILS on build errors**
+- ✅ Prisma client generation - **FAILS on generation errors**
+- ⚠️ npm audit - **Informational only** (continue-on-error: true)
+
+## Jobs That Are INFORMATIONAL ⚠️
+
+These jobs will show a **green checkmark** even if they find issues (they're meant to inform, not block):
+
+### 5. **secret-scanning**
+- ⚠️ Gitleaks - **Informational** (continue-on-error: true, --exit-code 0)
+- Purpose: Report secrets found in codebase, but don't block the build
+
+### 6. **dependency-scan**
+- ⚠️ Trivy vulnerability scan - **Informational** (--exit-code 0)
+- Purpose: Report HIGH/CRITICAL vulnerabilities, but don't block the build
+
+### 7. **sast-scan**
+- ⚠️ Semgrep - **Informational** (continue-on-error: true)
+- Purpose: Report security code patterns, but don't block the build
+
+### 8. **workflow-summary**
+- ✅ Always runs (if: always())
+- Purpose: Generate summary of all job results
+
+## Why Some Jobs Are Informational
+
+Security and dependency scanning jobs are kept as informational because:
+1. **False positives** - Security scanners can flag legitimate code
+2. **Historical context** - They scan all commits, including old ones
+3. **Non-blocking** - Teams can review and fix issues without blocking deployments
+4. **Visibility** - Results are still visible in the CI summary and step summaries
+
+## Database Creation
+
+The `|| true` on database creation commands is **intentional**:
+- Creating a database that already exists should not fail
+- Makes the step idempotent
+- Safe to run multiple times
+
+## Summary Step
+
+The test results summary step uses `|| true` for parsing errors:
+- Should always complete to show results
+- Parsing errors shouldn't fail the job
+- Actual test failures are caught by the test step itself
+
