Fix missing workspace lints & fix lints

[joshuamegnauth54]

Some of the workspace packages were missing the [lints] table. I enabled the lints then fixed the resulting errors.

📝 Walkthrough

Walkthrough

The pull request enables workspace lint inheritance, centralizes selected dependency versions, narrows internal Rust visibility, updates hash state representations, and removes or simplifies unused imports.

Changes

Rust workspace and API cleanup

Layer / File(s)	Summary
Workspace lint and dependency declarations Cargo.toml, crates/literal/Cargo.toml, crates/wtf8/Cargo.toml, crates/host_env/Cargo.toml	The root package and two crates inherit workspace lints. Selected host_env dependencies now use workspace-managed versions.
Internal API visibility boundaries crates/wtf8/src/concat.rs, crates/wtf8/src/core_char.rs, crates/wtf8/src/core_str.rs, src/shell/helper.rs	WTF-8 helpers and ShellHelper APIs are restricted to crate or parent-module scope. The completion context uses an explicit lifetime.
Source declarations and layout cleanup crates/common/src/float_ops.rs, crates/literal/src/float.rs, crates/stdlib/src/hashlib.rs	LOG10_2 uses a direct import, an unused import is removed, and two hash state structs use C layout with 16-byte alignment.
