fix: target build and cargo fmt issues (#50)

This pull request includes several changes to improve code organization
and update the toolchain configuration. The most important changes
include switching the Rust toolchain channel from nightly to stable and
reorganizing imports across multiple files for better readability and
consistency.

Toolchain update:

*
[`rust-toolchain.toml`](diffhunk://#diff-2b1bde2cf3a858b7bf7424cb8bcbf01f35b94dc80b925d9432cbab3319ca9b4eL2-R2):
Changed the Rust toolchain channel from `nightly` to `stable`.

Import reorganization:

*
[`src/cluster/scylla_cluster.rs`](diffhunk://#diff-a328ddcad66c7331981f0504e0e7c898b94bb7627b3dc3749bd2953f65a1a3ccL8-R8):
Reordered imports for `ClusterConfig` and `Compression` to improve
readability.
*
[`src/helpers/query_parameter.rs`](diffhunk://#diff-e6b61072519444eb27a091fedb6a7844299039dc6f7689a72ed61c8d16fa8cd1L2-R4):
Reorganized imports for `RowWriter` and `SerializationError` for
consistency.
*
[`src/helpers/query_results.rs`](diffhunk://#diff-c46f185a1370949dddf3212dc1936e62a30f230871954ff78ac2119f8611b0a5L3-R3):
Reordered `napi::bindgen_prelude` imports for better readability.
*
[`src/session/scylla_session.rs`](diffhunk://#diff-5d57737517755d2efee92f675121d13b74122292d129d971a4a1baff5a9f5032L9-R10):
Moved `napi::Either` import to maintain consistent import order.
*
[`src/session/topology.rs`](diffhunk://#diff-0021f8a05dab631179ba1f51c0e5c0371537704b22bb2d32b1069e0ceec30a45L5-R6):
Reorganized `scylla::transport::ClusterData` import for better
readability.
