Implement precreate functionality in session management

[faizanazim11]

Currently, session management provides a postcreate functionality that executes after the creation of tables and other meta information. To improve flexibility, we should implement a precreate functionality that runs before the creation of all meta.

Requirements:

• Add a precreate hook/option to session management.
• Ensure this is available for both synchronous and asynchronous implementations, mirroring the existing postcreate pattern.
• Document usage and expected behavior alongside postcreate for developers.

This enhancement will allow for custom logic or setup to run prior to database/table/meta creation, increasing extensibility for consumers of the library.
