feat: add cleanup command to readme

Introduce a new `cleanup` command that discovers and deletes archive tags, with options for force, remote handling, and local-only operations. Updated README with usage examples, added help entry, and expanded documentation to describe the command and its steps. Added corresponding implementation files (`cleanup.ts`) in both core and tools directories.

+1. **Archive tag discovery**: Finds all git tags matching the pattern `archive/*`

+2. **Local tag deletion**: Deletes all archive tags from the local repository
