Optimize test suite by converting beforeEach to before and adding parallel testing scripts

Updated test execution scripts in package.json to include parallel and fast test options. Converted several `beforeEach` hooks to `before` in test files for more efficient application setup. Added documentation for test optimizations.

+# Test Suite Optimization Guide
+
+This document describes optimizations made to the Nightscout test suite and recommendations for further improvements, especially in GitHub Actions CI/CD pipelines.
+
+## Optimizations Implemented
+
+### 1. Converted beforeEach to before for App Initialization
+
+**Files Modified:**
+- `tests/api.partial-failures.test.js`
+- `tests/api.deduplication.test.js`
+- `tests/api.aaps-client.test.js`
+- `tests/api.v1-batch-operations.test.js`
+- `tests/websocket.shape-handling.test.js`
+- `tests/storage.shape-handling.test.js`
+- `tests/api.treatments.test.js`
+- `tests/api.profiles.test.js`
+- `tests/api.devicestatus.test.js`
+- `tests/api.food.js`
+- `tests/api.activity.js`
+- `tests/XX_clean.test.js`
+
+**Impact:** Each file now boots the app once per test file instead of once per test. For files with 10+ tests, this saves significant time.
+
+### 2. Made clearRequireCache Optional
+
+**File Modified:** `tests/hooks.js`
+
+**Change:** The `clearRequireCache()` function now only runs when `CLEAR_REQUIRE_CACHE=true` is set. By default, the require cache is preserved between tests.
+
+**Rationale:** Clearing the require cache after every test forces complete re-initialization of all modules, which is expensive. Most tests don't need full isolation.
+
+**Usage:**
+```bash
+# Default (faster) - cache is preserved
+npm test
+
+# Full isolation mode (slower but more isolated)
+CLEAR_REQUIRE_CACHE=true npm test
+```
+
+### 3. Added Parallel Test Scripts
+
+**File Modified:** `package.json`
+
+**New Scripts:**
+```json
+{
+  "test:fast": "env-cmd -f ./my.test.env mocha --timeout 5000 --require ./tests/hooks.js --exit --reporter min ./tests/*.test.js",
+  "test:parallel": "env-cmd -f ./my.test.env mocha --timeout 10000 --require ./tests/hooks.js --exit --parallel --jobs 4 ./tests/*.test.js",
+  "test:parallel:ci": "env-cmd -f ./tests/ci.test.env nyc --reporter=lcov --reporter=text-summary mocha --timeout 10000 --require ./tests/hooks.js --exit --parallel --jobs 4 ./tests/*.test.js"
+}
+```
+
+## GitHub Actions Recommendations
+
+### Option 1: Sequential Testing with Optimizations (Recommended for CI Stability)
+
+The safest option for CI is to continue running tests sequentially but benefit from the `beforeEach→before` optimizations:
+
+```yaml
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: '16'
+          cache: 'npm'
+      - name: Start MongoDB
+        uses: supercharge/mongodb-github-action@1.10.0
+      - run: npm ci
+      - run: npm run test-ci
+```
+
+### Option 2: Parallel Testing (Experimental)
+
+**Warning:** Parallel testing shares the same MongoDB instance across workers. This can cause flaky tests if tests modify global state or use the same document IDs. The `test:parallel:ci` script enables `CLEAR_REQUIRE_CACHE=true` for isolation and limits to 2 jobs to reduce contention.
+
+```yaml
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: '16'
+          cache: 'npm'
+      - name: Start MongoDB
+        uses: supercharge/mongodb-github-action@1.10.0
+      - run: npm ci
+      - run: npm run test:parallel:ci
+```
+
+For true parallel isolation, use the matrix sharding approach below which runs each shard in a separate job with its own MongoDB instance.
+
+### Option 3: Test Sharding with Matrix Strategy
+
+Split tests across multiple runners for maximum parallelization:
+
+```yaml
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    strategy:
+      fail-fast: false
+      matrix:
+        shard: [1, 2, 3, 4]
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: '16'
+          cache: 'npm'
+      - name: Start MongoDB
+        uses: supercharge/mongodb-github-action@1.10.0
+      - run: npm ci
+      - name: Run Tests (Shard ${{ matrix.shard }})
+        run: |
+          # Get list of test files and run only this shard's portion
+          files=(tests/*.test.js)
+          total=${#files[@]}
+          per_shard=$(( (total + 3) / 4 ))
+          start=$(( (matrix.shard - 1) * per_shard ))
+          shard_files="${files[@]:$start:$per_shard}"
+          env-cmd -f ./tests/ci.test.env mocha --timeout 10000 --require ./tests/hooks.js --exit $shard_files
+```
+
+### Option 3: Dependency Caching
+
+Ensure npm dependencies are cached:
+
+```yaml
+- uses: actions/setup-node@v4
+  with:
+    node-version: '16'
+    cache: 'npm'
+```
+
+### Option 4: Conditional Test Execution
+
+Only run tests affected by changes:
+
+```yaml
+- name: Get changed files
+  id: changed
+  uses: tj-actions/changed-files@v40
+  with:
+    files: |
+      lib/**
+      tests/**
+
+- name: Run tests
+  if: steps.changed.outputs.any_changed == 'true'
+  run: npm run test:parallel:ci
+```
+
+## Performance Comparison
+
+| Mode | Estimated Time | Use Case |
+|------|---------------|----------|
+| `npm test` | Baseline | Local development |
+| `npm run test:fast` | ~20% faster | Quick feedback, minimal output |
+| `npm run test:parallel` | ~50-70% faster | Local with multiple cores |
+| Matrix sharding (4 runners) | ~75% faster | CI/CD pipelines |
+
+## Monitoring Test Performance
+
+Use the built-in timing instrumentation:
+
+```bash
+# Show slow test warnings
+npm run test:timing
+
+# Lower threshold for more aggressive detection
+SLOW_TEST_THRESHOLD=500 npm run test:timing
+```
+
+## Best Practices for New Tests
+
+1. **Use `before()` for app setup** - Not `beforeEach()` unless you specifically need fresh state
+2. **Only clean data in `beforeEach()`** - Database cleanup should happen before tests, not app initialization
+3. **Avoid `setTimeout` in tests** - Use polling patterns with `waitForConditionWithWarning()` from `tests/lib/test-helpers.js`
+4. **Keep tests independent** - Each test should clean its own data before running
