Note

Migrates sortable field storage to a Rust implementation with C FFI and updates callers accordingly.

• Replace C sortable.c/h vector logic with Rust sorting_vector crate exposed through sorting_vector_ffi; add sorting_vector_rs.h
• Update C callsites (document.c, doc_table.c, debug_commands.c) to use RSSortingVector_* API (New/Free/PutNum/PutStr/PutStrNormalize/Get/Length/GetMemorySize) and remove legacy NewSortingVector/SortingVector_Free
• Change string handling: sorting vector now accepts raw bytes; normalization is done in Rust (PutStrNormalize) instead of pre-normalizing in C
• Extend Rust value to work with byte strings (create_string(Vec<u8>), as_str_bytes) and add RSValue_NewCopiedString usage in FFI
• Add new crates/modules and exports (sorting_vector, sorting_vector_ffi) and wire through redisearch_rs entrypoint; adjust dependencies (drop thiserror from sorting_vector, add redis-module to value for MUSL)
• Update and expand tests to new APIs and byte-string expectations across rlookup and sorting_vector
• CI: minor YAML quoting cleanups and temporarily disable select benchmark jobs
