Pull request overview

Reverts the previously-added “large payload support” feature (PR #272) across the Java SDK, removing the blob-backed payload externalization module and all related client/worker/runtime hooks.

Changes:

• Removes the azure-blob-payloads module and its ServiceLoader-based provider wiring.
• Deletes large-payload APIs/helpers (e.g., PayloadStore, LargePayloadOptions) and removes payload interception/chunking logic from client and azurefunctions.
• Removes unit + integration tests that validated large payload externalization behavior.
