clone-issuelisted

Clone a Jira issue using `jirac`. Steps: 1. Check that `jirac` is available by running `jirac --version`. If it is missing, tell the user to install it with `cargo install jira-commands`. 2. Extract from the user's request: - source issue key - target project (if different from source) - override summary (optional) - assignee for the clone (optional — source assignee is NOT copied by default) - whether to delete the original after cloning (`--move`) 3. Run `jirac issue clone <KEY> [--project TARGET] [--summary TEXT] [--assignee EMAIL|me] [--move]`. 4. Confirm the cloned issue key clearly. Notes: - Copies: summary, description, type, priority, labels, components, fix versions. - Does NOT copy: assignee (unless `--assignee` is set), comments, attachments, worklogs. - `--move` deletes the original issue after cloning. Examples: - "clone PROJ-123" → `jirac issue clone PROJ-123` - "clone PROJ-123 to project NEWPROJ" → `jirac issue clone PROJ-123 --project NEWPROJ` - "clone PROJ-123 with summary 'Copy: login bug'" → `jirac issue clone PROJ-123 --summary 'Copy: login bug'` - "move PROJ-123 to OTHER project" → `jirac issue clone PROJ-123 --project OTHER --move`
