Fixes #14897
This PR fixes a SARIF parser crash when importing valid SARIF 2.1.0 reports with empty
results, emptydriver.rules, and missing or emptytool.extensions.Previously the parser assumed that
extensions[0]always exists whendriver.rulesis empty:rules_array = run["tool"]["extensions"][0].get("rules", [])This could lead to:
IndexError: list index out of rangeThe fix safely iterates through available extensions and collects rules only if they are present, avoiding unsafe indexing and correctly handling spec-compliant SARIF files with no findings.
Tested with the minimal SARIF sample attached in issue #14897.
