Dead code lint globally suppressed with -A dead_code

[brandonrc]

Problem

Clippy runs with -A dead_code applied workspace-wide, suppressing all dead code warnings. This masks unused functions, imports, and types that accumulate over time and increase maintenance burden.

Suggested Fix

1. Remove the -A dead_code flag from the Clippy configuration
2. Fix all resulting warnings (remove dead code or mark intentionally-unused items with #[allow(dead_code)] individually with a comment explaining why)
3. This cleanup will also reduce binary size
