Stages and commits git changes using semantic commits with logical grouping. Use when the user asks to "commit my changes", "commit these changes", "commit staged files", "commit unstaged files", "commit specific files", "make a commit", "create commits", or /commit. Defaults to staged-only scope. Warns if unstaged changes exist. Groups related changes into separate semantic commits with meaningful titles and body descriptions. Supports three scopes: staged (default), unstaged, or specific files/paths provided by the user.
