fix #2180 : pin home and wabt versions for Rust 1.85 compatibility

[SarthakRawat-1]

Summary

This PR fixes #2180 aka the extension tests that were failing due to dependency incompatibility with Rust 1.85.

Problem

The extension tests in libsql-sqlite3/test/rust_suite were failing because:
The home crate version 0.5.12 requires Rust 1.88, but the project uses Rust 1.85
Older versions of wabt-sys had CMake compatibility issues requiring newer CMake versions

Solution

Pin home crate to version =0.5.9 which is compatible with Rust 1.85
Downgrade wabt from 0.10.0 to 0.9.1 to avoid CMake issues
Explicitly add the home dependency in Cargo.toml for clarity
