feat: add molecule navigation commands (bd-sal9, bd-ieyy)

Add bd mol current: Shows current position in molecule workflow
- Displays all steps with status indicators (done/current/ready/blocked/pending)
- Infers molecule from in_progress issues when no ID given
- Supports --for flag to check another agent's molecules

Add bd close --continue: Auto-advances to next molecule step
- After closing, finds parent molecule and next ready step
- Auto-claims next step by default (--no-auto to skip)
- Shows molecule completion message when all steps closed
