Implements a new `/core:commit` command that analyzes staged changes to generate a conventional commit message. The command supports three main modes of operation: - `/core:commit`: Automatically generates a commit message based on the content of the staged files. - `/core:commit "custom message"`: Uses the provided string as the full commit message. - `/core:commit --amend`: Amends the last commit with the new message. Message generation includes several heuristics: - **Commit Type:** Determined by file paths (e.g., `_test.go` -> `test`) and diff content (e.g., keywords like `fix` or `refactor`). - **Scope:** Inferred from the most common directory name among the staged files. - **Summary:** Extracted from function or class names in the diff, or defaults to a file-based summary. - **Co-Author:** A `Co-Authored-By` trailer is automatically appended. This feature streamlines the development workflow by automating the creation of descriptive and conventional commit messages.
