Greptile Summary

Pure structural refactor that extracts the package fetch/import pipeline (~930 lines) from commands/install/mod.rs into a new commands/install/fetch.rs module. No logic is changed — functions are moved verbatim and the public API surface is preserved via re-exports.

• fetch.rs hosts import_local_source, fetch_packages, fetch_packages_with_root, remap_indices_to_contextualized, and version_from_dep_path with the same visibility rules they had in mod.rs (pub(super) for internal helpers, pub(in crate::commands) for the aube fetch-facing entry point).
• mod.rs drops the now-redundant local imports (rayon, dep_path_to_filename, is_likely_native_build, git_prepare helpers) and re-exports fetch_packages at pub(super) so sibling commands can still reach it through install::fetch_packages.

Confidence Score: 5/5

Safe to merge — the code is moved byte-for-byte; the PR's own validation (fmt, check, clippy, tests) covers the changed paths.

Every function body in fetch.rs is a verbatim copy of what was in mod.rs; the only changes are module boundaries and import adjustments. The re-export visibility (pub(super) for fetch_packages) is semantically equivalent to pub(in crate::commands) from the sub-module's perspective, so no callers lose access.

No files require special attention; both files are straightforward module restructuring with no logic edits.
