Rodrigo Correia 729e1e6920 feat(db): add occ db:info, db:size, db:index-usage and db:locks ... Implements RFC #59422. Adds four read-only diagnostic commands to the occ CLI for administrators to inspect database health without needing external tools: - db:info: shows engine version and key config variables with health check against recommended values - db:size: lists all tables ordered by total disk usage - db:index-usage: reports unused indexes via performance_schema (MySQL) or pg_stat_user_indexes (PostgreSQL) - db:locks: detects active blocking transactions and deadlocks All commands support MySQL/MariaDB and PostgreSQL. A --json flag is available for automated parsing. Includes 31 unit tests.
