🔧 Blanket #![allow(dead_code)] masks genuinely unused code

[ajianaz]

Description

src/main.rs:3 has #![allow(dead_code)] for the entire crate. Several public functions have no callers outside of tests:

• config/providers.rs:first_detected_preset()
• git/files.rs:list_tracked_files(), list_all_changed_files(), filter_by_globs(), is_gitignored()
• git/diff.rs:is_inside_git_repo()
• engine/review.rs:review_diff() (non-stream variant), scan_project()

Suggested Fix

Remove the blanket allow. Add targeted #[allow(dead_code)] only where needed. Remove genuinely unused functions.
