Improve test coverage and fix failing test
- Fix InverterTest.ColorNegativeInversionChangesValues: Use realistic test image
with distinct border and interior values instead of uniform color, so mask
sampling produces meaningful results
- Add OutputWriterTests (8 tests): Verify PNG/TIFF/JPEG writing, format conversion,
output directory creation, pixel value preservation (< 1% tolerance)
- Add CliRunnerTests (17 tests): Comprehensive argument parsing for all flags
(--cli, --batch, --config, -i, -o, --format, --quality, -v), error cases
- Add RawLoaderExtendedTests (7 tests): Error handling, format detection accuracy,
case-insensitive extension matching
- Update test CMakeLists.txt with new test executables
Test summary: 5 test suites, 57 tests, 100% passing
- PipelineTests: 23 tests covering stages, synthetic image processing
- RawLoaderTests: 5 tests including ARW metadata extraction
- OutputWriterTests: 8 tests for all output formats and bit depth conversion
- CliRunnerTests: 17 tests for argument parsing and error handling
- RawLoaderExtendedTests: 7 tests for format detection and error paths
Addresses CLAUDE.md requirements:
- Tests use RAW golden files (DSC09246.ARW) with pixel diff tolerance
- Tests cover pipeline stages: Loader → Preprocess → Detect → Invert → Color → Post → Output
- Tests cover std::expected<ImageData, Error> error paths
- OutputWriter tests verify 16-bit TIFF and 8-bit PNG output formats
