Fix DatabaseTruncation in Testbench

[binaryfire]

Summary

This change makes DatabaseTruncation work through Hypervel Testbench with the same public behavior it already has through the Foundation test case.

It also fixes the database lifecycle exposed by that integration:

• preserve in-memory SQLite databases across Testbench application recreation;
• classify URL-based SQLite connections through the same normalized configuration path as the connection factory;
• load migration paths at the correct point for initial, retained in-memory, and persistent database lifecycles;
• isolate method-level WithMigration schemas from the retained class schema.

Problem

Testbench overrides the Foundation database-concern setup order so it can process requirements and attributes before migrations run. That override invoked RefreshDatabase, DatabaseMigrations, and DatabaseTransactions, but omitted the existing DatabaseTruncation concern. Tests could declare the trait without receiving its migration or truncation lifecycle.

Adding the missing invocation exposed two Testbench-specific constraints. Each test method recreates the application, which also creates a new in-memory SQLite PDO, and Testbench can register migrations after the application has booted. Without retaining the PDO and choosing the correct migration path owner, later tests either lose the migrated schema or run package migrations against a connection that is about to be replaced.

The existing SQLite memory checks also inspected raw configuration keys. Supported URL-only configurations were therefore missed, and a URL that overrides discrete driver values could be classified using the wrong driver.

Implementation

SQLiteDatabase::isInMemoryConfiguration() now normalizes connection configuration with the database URL parser before checking the driver and database value. RefreshDatabase, Testbench, and DatabaseTruncation share this classifier. Missing connection records retain their existing failure path, while malformed URLs fail through the configuration parser.

DatabaseTruncation now participates in parallel database setup and retains every configured in-memory SQLite PDO after the initial migration. Later application instances restore those PDOs before truncation hooks run and replace the old application event dispatcher with the current one. Persistent databases keep the existing direct truncation path and avoid resolving database services when no PDO is cached.

Testbench now invokes DatabaseTruncation after database requirements and migration attributes are applied. Default migration paths are registered for the initial migration and retained in-memory lifecycle. Persistent databases that were already migrated continue through the rollback-capable migration processor. Method-level WithMigration attributes reset retained state before and after the method so their temporary schema cannot leak into sibling tests.

The todo list records a related parallel-testing gap for persistent connections configured only through a URL. That needs URL-aware worker database rewriting or a clear unsupported-configuration failure; this change does not add a narrow workaround.

Compatibility and performance

This does not change existing public method signatures or the purpose of any testing concern. It restores the existing DatabaseTruncation contract for Testbench users.

The added work is limited to test setup. Normal discrete connection configuration takes the parser's no-URL path, persistent database runs take the empty PDO-cache fast path, and production application runtime is unaffected.

Testing

• SQLite configuration classification, including URL precedence and URL-only in-memory connections
• Foundation refresh and truncation state handling
• Testbench initial and subsequent application lifecycles
• persistent already-migrated SQLite databases
• method-specific migration isolation and class-schema restoration
• the full formatting, static-analysis, parallel-test, and Testbench checks through composer fix
