@ofekshenawa thank you for contributing this. I can see there are panics that were in the code even before we added this change, but let's make sure we don't panic during the execution of a command. Maybe the arguments were dynamically build, and returning an error should be sufficient way of noting that they are wrong, panicking will stop the whole execution of the application (if not recovered) and we should not do that.

Implements comprehensive support for the VAMANA vector index algorithm introduced in Redis 8.2+.
Key Changes
Core Implementation : Added FTVamanaOptions struct with full parameter support (distance metrics, vector types, compression, advanced tuning)
Feature Set : Supports L2/COSINE/IP distance metrics, FLOAT16/FLOAT32 vector types, LVQ8 compression, construction window size and graph max degree
Tests: Includes test suite covering VAMANA functionality, distance metrics, compression scenarios, and parameter combinations
