Remove check credit balance API endpoint and related models

[jfrench9]

Summary

Removes the check_credit_balance API endpoint and its associated response model from the robosystems_client package, simplifying the credits API surface. Minor adjustments were made to related modules to maintain consistency.

Key Accomplishments

• Removed check_credit_balance endpoint: Deleted the full implementation (~290 lines) of the check credit balance API, including sync/async variants and detailed/shorthand client methods.
• Removed associated response model: Deleted the CheckCreditBalanceResponseCheckcreditbalance model and cleaned up its references from the models __init__.py.
• Updated adjacent modules: Minor adjustments to get_credit_summary and get_materialization_status to ensure continued consistency after the removal.

Breaking Changes

⚠️ This is a breaking change.

• The check_credit_balance API function (including sync, sync_detailed, asyncio, and asyncio_detailed variants) is no longer available.
• The CheckCreditBalanceResponseCheckcreditbalance model has been removed from robosystems_client.models.
• Any consumers relying on these endpoints or models will need to migrate to an alternative (e.g., get_credit_summary) or remove their usage.

Testing Notes

• Verify that existing functionality around get_credit_summary and get_materialization_status continues to work as expected.
• Confirm no remaining internal references to the removed endpoint or model exist across dependent services or client integrations.
• Ensure any SDK documentation or generated API references are regenerated to reflect the removal.

Infrastructure Considerations

• Downstream services and consumers of the robosystems_client package should be audited for usage of the removed endpoint before upgrading to this version.
• Consider coordinating this release with a version bump to signal the breaking change (e.g., a major or minor version increment depending on semver policy).
• If the corresponding server-side endpoint is also being deprecated, ensure the rollout is sequenced appropriately (clients updated before or alongside server changes).
