Add comprehensive test coverage for parser modules and expand config testing: - parser/bed.rs (14 tests): Header generation, multi-chromosome parsing, 12-column BED support, malformed line handling, empty files, varying metadata columns, scientific notation rejection, negative/large coordinates, and chunked reading behavior - parser/gtf.rs (14 tests): Comment handling, multi-chromosome annotations, custom ID tags, exon-only GTF files, full GTF format with gene/transcript entries, multiple isoforms per gene, invalid strand filtering, negative strand exon numbering, max gene length tracking, and empty/comment-only files - Error type display tests (9 tests): Verify Display, Debug, and std::error::Error trait implementations for ParseStrandError, ParseAreaError, and ParseReportLevelError - Config extended tests (12 tests): Default/custom ID tags, all ReportLevel variants, large distance values, max_lookback calculations with various TSS/promoter/TTS values, rule parsing with duplicates, order preservation, Debug output, Clone independence, and boundary values Update SHARED_TASK_NOTES.md with current test counts (168 unit tests, 223 total) and revised next steps for continued coverage improvements.
Fix cargo fmt check failure by reformatting the parse_rules function call in test_config_parse_rules_preserves_order test. Co-Authored-By: Claude (claude-opus-4-5) <noreply@anthropic.com>
