Gerrit CLI and SDK - A modern CLI tool and TypeScript SDK for Gerrit Code Review, built with Effect-TS

Examples:
  # Retrigger CI for the change in HEAD commit (auto-detected)
  $ ger retrigger

  # Retrigger CI for a specific change
  $ ger retrigger 12345

Notes:
  - The retrigger comment is saved in config (set during "ger setup" or prompted on first use)
  - Auto-detection reads the Change-Id footer from HEAD commit`
