Add CorePluginMockBukkitTest covering onEnable/getInstance, getMiniMessage, registryAccess, and getTimeProvider via MockBukkit. Add DatabaseErrorHandlingTest covering shutdown idempotency when dataSource is already closed, tableExists with getMetaData and getTables SQLExceptions, case-insensitive table name matching, and non-existent table lookups.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds tests, but one test constructs a registry directly and another does not clear the plugin singleton after teardown, which can bypass lifecycle guarantees or affect later tests; the change is otherwise low risk once these bounded test-isolation issues are addressed.

Access DriverRegistry through RegistryAccess.
Do not create DriverRegistry with new. Obtain the registry through RegistryAccess or provide it through the test fixture. This keeps registry lifecycle and service access consistent with the framework boundary.
As per coding guidelines, “Never instantiate managers or registries directly; access all services through RegistryAccess singleton”.
