Pull request overview

This PR updates the SQLite schema used by cve-query to normalize previously inlined CVE/package metadata into dedicated tables, and extends the query tool/test suite accordingly.

Changes:

• Normalize CVE fields into new tables (references, bugs, discovered-by, GHAS alerts, OCI scan reports, pkg patches/tags/priorities/close-dates).
• Add insert helpers for the new tables and batch DB population via commit=False + a final commit().
• Harden execute_query() by enforcing read-only queries via SQLite authorizer, and expand/adjust tests for the new schema and data sources.

cvelib/sql.py	Adds new normalized tables + insert helpers, batches commits during DB build, and restricts execute_query() to read-only via set_authorizer().
tests/test_sql.py	Updates expectations for the new schema, adds coverage for new insert helpers, and extends CLI tests to cover GHAS/scan data ingestion and read-only query enforcement.
