Add `bd move <id> --to <rig|prefix>` command that:
- Creates a copy of the issue in the target rig
- Remaps dependencies pointing TO the moved issue to external refs
- Removes dependencies FROM the moved issue (with user notice)
- Closes the source issue with a redirect note
Key features:
- Forgiving target spec (accepts rig name, prefix, or prefix without hyphen)
- Preserves all issue fields, labels, and dependency metadata
- Handles cross-rig moves properly using external references
- Includes --keep-open and --skip-deps flags for flexibility
Tested on real misfiled beads (hq-c21fj → bd-c0b6, hq-q3tki → gt-quf4c).
