v0.3.1

Highlights

• Parallel Phase 2: fetch/pull now runs concurrently via a thread pool (previously sequential)
• Fork safety: child process uses execve with pre-resolved g_git_path; unsafe execvp fallback removed
• Spinner: async-signal-safe write(2) output, explicit Phase 1 → Phase 2 transition with separate spinner labels
• Bounded write length on snprintf truncation (long paths)

Fixes

• Spinner no longer hangs after Phase 1
• Fetch correctly reports "up to date"
• Branch-name parsing fix
• Last-commit time refreshes after branch switch
• Locale handling consistent across child processes
