Summary

This PR cleans up a set of low-risk Rust warnings across several Lind-specific crates and related local codepaths.

What is fixed

This PR includes conservative warning cleanup in:

  • wasmtime-wasi
  • threei
  • wasi-common
  • wasmtime-lind-multi-process
  • wasmtime-lind-common
  • typemap (partial)
  • rawposix (partial)
  • wasmtime (partial)

The applied fixes are limited to low-risk changes such as:

  • removing unnecessary mut
  • renaming intentionally unused variables to _...
  • removing unused imports
  • applying straightforward lifetime syntax cleanup
  • removing clearly unnecessary unsafe

Why some warnings were intentionally left unresolved

I did not keep every cargo fix suggestion.

  • wasmtime: some warnings are in behavior-sensitive runtime code (for example signal handling, code memory, and low-level runtime internals), so I only kept clearly safe changes and reverted riskier ones.
  • typemap: I intentionally reverted the cargo fix changes in typemap/src/network_helpers.rs because they introduced suspicious pattern rewrites and unreachable-pattern warnings.
  • rawposix: I kept straightforward cleanup, but left warnings that appear to require manual semantic review, especially around ignored Results, unused assignments, and logic-sensitive comparisons.

Follow-up issues

  • Remaining wasmtime warnings in low-level runtime code need manual review.
  • typemap/src/network_helpers.rs should be revisited separately because some auto-fix rewrites appeared unsafe.
  • Some rawposix warnings were intentionally left for manual semantic review.

Partially addresses #624
