feat: add usage examples for all drivers

Create explicit, self-contained examples for:
- MySQL (PDO, Doctrine DBAL)
- Redis (Ext-Redis, Predis)
- Mongo (MongoDB\Database)

Each example demonstrates explicit driver instantiation, adapter wrapping,
and retrieval via getDriver().

Examples are intentionally devoid of autoloaders or bootstrap logic
to emphasize their role as snippet references for integration.
