* fix: address review findings in test harness
- Fix slice mutation via append in ConsoleReport (pre-allocate allTests)
- Close file before checksum verification (not deferred)
- Use math.Round instead of hand-rolled round() function
- Use os.UserHomeDir() with error handling instead of os.Getenv(HOME)
- Clean up temp dirs on download failure via deferred cleanup
- Move Docker image cleanup defer before g.Wait() in CompareSchema
- Validate checksum is 64-char hex SHA256 in parseChecksum
- Check f.Close() errors explicitly on all write paths
- Replace hand-rolled join/repeat/splitLines with strings stdlib
- Extract resolveSetup() helper to deduplicate cmd boilerplate
- Validate --output flag is 'console' or 'json'
- Sort map keys for deterministic input/env ordering
- Move binary download temp dir to ~/.cache/cog-harness/bin/
- Extract setGitHubAuth() helper for DRY token logic
- Use local vars in CompareSchema goroutines to avoid concurrent writes
- Use filepath.WalkDir + skip symlinks in copyDir
- Cleanup() collects and returns errors via errors.Join
* fix: address low-severity review findings in test harness
- Send checksum success message to stderr for consistent diagnostic output
- Check os.MkdirAll error in buildCogFromRef wheel dir creation
- Thread context.Context through cloneRepo, extractSchemaLabel, prepareModel
- Add tests for extractOutput (7 cases) and report package (round, JSONReport)
- Fix double error printing in main.go with SilenceErrors
- Include failed model names in error messages for run/build/schema-compare
