feat: add a Surreal Eloquent query foundation

[ibourgeois]

Summary

• turn the surreal database connection into a real data connection instead of a schema-only shim
• add a Surreal query builder that supports the core Eloquent operations needed for standard model usage
• prove the new path with a real User Eloquent test on DB_CONNECTION=surreal

Verification

• vendor/bin/pint --dirty --format agent
• php artisan test --compact tests/Unit/SurrealHttpClientTest.php tests/Feature/SurrealSchemaDriverTest.php tests/Feature/SurrealWorkspaceModelTest.php tests/Feature/SurrealEloquentDriverTest.php

Closes #117

Pull request overview

Adds an initial SurrealDB-backed Laravel Query Builder / Eloquent foundation so the surreal connection can be used for standard model workflows (e.g., User::query()), with a feature test proving basic CRUD against a real Surreal runtime.

Changes:

• Introduces a custom SurrealQueryBuilder and wires it into SurrealSchemaConnection::query().
• Extends SurrealSchemaConnection to execute select/insert/update/delete operations via SurrealQL over SurrealHttpClient.
• Adds a feature test that boots a local Surreal instance and validates common User Eloquent operations on DB_CONNECTION=surreal.
