v0.15.1

Fixed

• zsh completion via git's own git-completion.zsh wrapper (Homebrew git, Apple Command Line Tools) now completes non-empty words. Previously any typed prefix — git hunk add 9<TAB>, git hunk list --sta<TAB>, even a unique hash prefix — completed nothing, because the wrapper's dispatch context breaks the compsys engines behind _describe and _arguments option matching. The _git_hunk bridge is now a self-contained wrapper-native completer built on raw compadd/_wanted/_files, and hash candidates gain oneline-style descriptions (9ab03ef foo 0 0 new file). zsh's builtin _git dispatch and direct git-hunk completion are unchanged.

Added

• Interactive completion regression tests (tests/test_completions.sh): drives real TAB completion in a pty for both the direct and git hunk wrapper dispatch paths, with hash-prefix overlap guaranteed by construction. Skips gracefully when zsh/zpty or a git-completion.zsh wrapper is unavailable.
