Subject: [PATCH] feat(cli): add --dry-run flag to preview commit message
 without committing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a --dry-run option that runs the full analysis and message generation
pipeline, prints the resulting commit message to stdout, then exits with
code 0 — skipping the interactive prompt and git commit entirely. Closes #29.
