Move pour and ephemeral under bd mol subcommand (bd-2fs7)

For consistency, all molecule operations are now under bd mol:
- bd mol pour <proto>     - create persistent mol
- bd mol ephemeral <proto> - create ephemeral mol
- bd mol ephemeral list   - list ephemeral issues
- bd mol ephemeral gc     - garbage collect old ephemeral issues

This aligns with existing mol subcommands: bond, squash, burn, etc.
