fix: update metrics crate and remove unused import for rustc 1.94 compat

[mrmodolo]

Summary

This PR fixes a build failure with rustc 1.94+ and removes an unused import warning.

Changes

• Cargo.lock: Bump metrics from 0.24.1 to 0.24.3 to fix E0521 (borrowed data escapes outside of associated function) caused by a recent compiler change that rejects raw pointer casts extending lifetimes on trait objects. See Tracking Issue for breaking raw pointer casts of trait objects rust-lang/rust#141402
• src/opts/cli.rs: Remove unused command import from clap (flagged as warning)

Reproduction

Building with rustc 1.94.0 fails with:

error[E0521]: borrowed data escapes outside of associated function
--> metrics-0.24.0/src/recorder/mod.rs:156:13

Fixed by running:
bash
cargo update -p metrics
cargo fix --bin "inlyne" -p inlyne --allow-dirty
