fix: add bandit to dev dependencies and improve security

Changes:
1. Add bandit[toml]>=1.7.0 to dev dependency group for CI security scans
2. Update fastapi to >=0.118,<0.119 and add starlette>=0.47.2,<0.48
   to address security vulnerabilities (GHSA-2jv5-9r88-3w3p)
3. Replace SHA-1 with SHA-256 in file comparison module for better
   cryptographic security

Root cause of CI failure:
- Bandit was configured in pyproject.toml but not listed as a dependency
- CI workflow ran 'uv run bandit' causing "No such file or directory" error

Security improvements:
- SHA-256 is more resistant to collision attacks than deprecated SHA-1
- Updated dependencies address known vulnerabilities
- Bandit static analysis now properly configured for CI/CD pipeline

Verified:
✅ uv run bandit --version works (returns 1.8.6)
✅ Bandit scan runs successfully
✅ All 382 tests pass in ~0.4 seconds
✅ Code quality checks pass (ruff format, ruff check, mypy)

 DLsite Classification Manager is a high-performance DLsite works classification and management tool with a modern web interface and complete API functionality. It automatically extracts and manages metadata for DLsite content (identified by codes: RJ, BJ, VJ, RE, BE, VE).
 
-## Running Unit Tests
+## Code Quality Checks
 
-**IMPORTANT: Always run tests using the standardized script to ensure consistent results.**
+**CRITICAL: Always run these checks after ANY code changes before committing.**
 
-To verify unit tests after any code changes:
+### Required Quality Checks (Run in Order)
 
+1. **Format Code** (auto-fixes formatting issues):
+   ```bash
+   uv run ruff format .
+   ```
+
+2. **Lint and Auto-fix** (auto-fixes linting issues):
+   ```bash
+   uv run ruff check --fix .
+   ```
+
+3. **Type Check** (validates type hints):
+   ```bash
+   uv run mypy .
+   ```
+
+4. **Run Tests** (validates functionality):
+   ```bash
+   ./run_tests.sh
+   ```
+
+### Quick Quality Check Script
+
+Run all checks at once:
 ```bash
-./run_tests.sh
+uv run ruff format . && uv run ruff check --fix . && uv run mypy . && ./run_tests.sh
 ```
 
-This script ensures:
-- ✅ Tests are run with correct coverage settings
-- ✅ Only tested modules are measured (100% coverage for URL and security modules)
-- ✅ Consistent results between all developers
+**These checks ensure:**
+- ✅ Consistent code formatting (PEP 8 compliant)
+- ✅ No linting errors or code smells
+- ✅ Type safety and correctness
+- ✅ All tests pass with required coverage
 - ✅ Fast execution (~0.4 seconds for 81 tests)
