v1.2.0 - Critical Taxonomy Usage Detection Fix

Critical Bug Fix

Problem: All taxonomy terms were incorrectly reported as 'Not used (safe to delete)' regardless of actual usage. This affected production sites where terms had thousands of node references.

Root Cause: Scout only queried the taxonomy_index table, but many Drupal sites (including those with field-based taxonomy) don't populate this table. All usage data resides in node__field_* tables instead.

Solution: Enhanced taxonomy usage detection to query BOTH:

1. taxonomy_index table (for sites that use it)
2. All node__field_* tables directly (for field-based taxonomy)

This ensures accurate usage detection regardless of site configuration.

Changes

• Enhanced _get_term_usage_from_drush() to query field data tables directly
• Added verify_database_connection() for pre-flight connectivity checks
• Added check_module_enabled() to validate required modules
• Enhanced error handling in run_drush_command()
• Added check_scout_health() tool for diagnostics
• Enhanced get_watchdog_logs() with dblog module check
• Added comprehensive diagnostics to show query methods and results

Testing

• Tested on DDEV development site with real taxonomy data
• All 31 tests passing

Breaking Changes

None - backward compatible with all existing Scout deployments
