jedarden dff76d779d docs(bf-5txw9): verify path normalization already implemented in fixture_discovery

The normalize_path() function in fixture_discovery.rs (lines 56-114) already provides:
- Symlink resolution via canonicalize()
- Relative component handling (., ..)
- Absolute path conversion
- Fallback for non-existent paths

All 13 tests pass, including specific normalization verification tests:
- test_fixture_paths_are_absolute
- test_normalized_paths_no_relative_components
- test_normalized_paths_work_in_test_context
- test_normalized_paths_are_consistent
- test_category_discovery_returns_normalized_paths

Acceptance criteria met:
✅ Paths are absolute or consistently test-relative
✅ Symlinks and relative components resolved
✅ Paths work in test context

No code changes required - verification note documents existing implementation.

bf-5txw9: Add path normalization for fixture discovery

Summary

Path normalization was already implemented in the fixture_discovery.rs module as part of the basic discovery implementation (bf-6cc3z).

Implementation Status

The normalize_path() function (lines 56-114 in fixture_discovery.rs) provides comprehensive normalization:

Features Implemented

Symlink Resolution: Uses Path::canonicalize() to resolve symlinks and get absolute paths
Relative Component Handling: Component-based normalization removes . and .. components
Absolute Path Conversion: Converts relative paths to absolute paths based on current directory
Fallback for Non-existent Paths: Handles paths that don't exist gracefully with component-based normalization

Code Coverage

The normalization is applied in:

discover_fixtures_flat() - line 195
discover_fixtures_in_dir() - line 233
All discovery functions transitively through these

Verification - Test Results

All 13 fixture discovery tests pass:

running 13 tests
test tests::test_category_discovery_returns_normalized_paths ... ok
test tests::test_discover_fixtures_by_category ... ok
test tests::test_discover_fixtures_flat ... ok
test tests::test_discover_all_fixtures ... ok
test tests::test_fixture_categories ... ok
test tests::test_fixture_sorting ... ok
test tests::test_fixture_paths_are_absolute ... ok
test tests::test_fixtures_root_exists ... ok
test tests::test_nonexistent_category ... ok
test tests::test_fixture_statistics ... ok
test tests::test_normalized_paths_are_consistent ... ok
test tests::test_normalized_paths_no_relative_components ... ok
test tests::test_normalized_paths_work_in_test_context ... ok

test result: ok. 13 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out

Acceptance Criteria Status

✅ Discovered paths are absolute or consistently test-relative: test_fixture_paths_are_absolute verifies all paths are absolute
✅ Symlinks and relative components are resolved: test_normalized_paths_no_relative_components verifies no /./ or /../ in paths
✅ Paths work in test context: test_normalized_paths_work_in_test_context verifies all normalized paths exist and are readable

Files

crates/pdftract-cli/tests/fixture_discovery.rs - Lines 56-114 (normalize_path function), applied at lines 195, 233
Tests: Lines 438-514 cover normalization verification

Conclusion

The path normalization requirement for bf-5txw9 is already fully implemented and tested. No additional code changes are required.
