## What Was Built

### 1. Performance Test Suite (450 lines)
**File:** `tests/performance/test_cli_startup.py`

- Lazy loading overhead
- E2E startup sequences

**13+ comprehensive tests**

### 2. Integration Test Suite (650 lines)
**File:** `tests/integration/test_cli_integration.py`

Verifies optimizations don't break functionality:
- All command groups (config, project, item, link, mcp)
- Lazy loading mechanisms
- Shell completion
- Alias system
- Error handling
- Cache behavior
- Regression prevention

**35+ integration tests**

### 3. Benchmark Suite (550 lines)
**File:** `tests/performance/test_cli_benchmarks.py`

Detailed performance benchmarking:

**20+ benchmarks with pytest-benchmark integration**

### 4. Test Execution Script (400 lines)
**File:** `tests/performance/run_cli_optimization_tests.sh`

Automated test execution with 5 modes:
- `--quick`: Fast validation (2 min)
- `--benchmarks`: Benchmarks only (5 min)
- `--full`: Complete suite (10 min)
