fix(ci): persist sccache and align documentation tests with nightly - #28

Conversation
Enable sccaches GitHub Actions backend so compiler artifacts can be reused across CI runs while preserving the existing rust-cache target caching behavior. Run documentation tests explicitly on nightly, matching the toolchain already required by the documentation build. Simplify the documentation CI job to install nightly directly instead of using stable for doctests. Apply the persistent sccache configuration to the existing MSRV, feature-check, test, documentation, and Clippy jobs without otherwise changing their cache policy.

This updates Steda’s Rust CI caching while preserving the existing Cargo target cache behavior.
The main fix is enabling sccache’s GitHub Actions backend so compiler artifacts persist across CI runs instead of being written only to ephemeral runner-local storage.
The documentation job is also simplified to use nightly directly. Steda already relies on nightly for documentation-related work, so installing stable first and then switching toolchains was unnecessary.
