Pull request overview

This PR extends test coverage for hybrid search scorer support and adds experimental annotations to hybrid_search methods. The changes validate that multiple scoring algorithms (TFIDF, TFIDF.DOCNORM, BM25, BM25STD, BM25STD.TANH, DISMAX, DOCSCORE, HAMMING) work with hybrid search operations.

Changes:

• Added new test method test_hybrid_search_query_with_supported_scorer to validate multiple scoring algorithms
• Updated documentation for scorer parameter to include newly tested scoring algorithms
• Added @experimental_method() decorator to both sync and async hybrid_search methods

🤖 Augment PR Summary

Summary: This PR expands hybrid-search scorer coverage and improves experimental/deprecation utilities for async APIs.

Changes:

• Marks `ft().hybrid_search()` (sync + asyncio) as experimental via `@experimental_method()`.
• Updates HybridSearchQuery scorer documentation to include additional server-supported algorithms.
• Refactors `deprecated_function`, `deprecated_args`, `experimental_method`, and `experimental_args` to correctly wrap coroutine functions and avoid mutable default parameters.
• Adds new sync and asyncio unit tests validating emitted warnings and metadata preservation for the decorators.
• Adds a Redis-version-gated test that iterates through multiple supported scorers to ensure the server accepts each value.

Technical Notes: Decorators now use inspect.iscoroutinefunction() and an argument-filtering helper to keep behavior consistent across sync/async call sites.
