Greptile Summary

This PR is a pure structural refactor: four helper clusters that had accumulated at the bottom of commands/install/mod.rs are extracted into focused sibling modules (lockfile_dir, summary, sweep, unreviewed_builds), and UnreviewedBuild's visibility is widened from pub(super) to pub(in crate::commands::install) so the new warning module can reach it.

• All extracted functions are mechanically identical to their originals; the only non-trivial adjustment is should_print_human_install_summary in summary.rs updating its super path to super::super::global_output_flags(), which correctly reaches the same commands::global_output_flags that super::global_output_flags() resolved to from mod.rs.
• Call sites in mod.rs are updated to namespace-qualified paths (e.g. unreviewed_builds::emit_warning, unreviewed_builds::from_state), improving readability without altering runtime behavior.

Confidence Score: 5/5

Safe to merge — this is a mechanical code-motion refactor with no logic changes.

Every moved function is a verbatim copy of its original; the one path-depth adjustment (super::super in summary.rs) resolves to the same target; cargo fmt/check/clippy/test are all listed as passing. No logic, behavior, or public API is altered.

No files require special attention.
