Pull request overview

Adds an explicit --git-dir flag to prek install so users can force the hook installation target directory, and extends the test suite to cover this behavior (including interaction with core.hooksPath).

Changes:

• Add --git-dir <GIT_DIR> to the install subcommand CLI args.
• Wire the parsed git_dir through main.rs into the install implementation.
• Add integration tests verifying hook installation into a custom git directory and behavior when core.hooksPath is set.
