msg run command's main package source code are hidden

[piux2]

          There is no straightforward method to identify the source code of the main package that was executed previously using the msg run command, as it is not persisted. Consequently, we are unable to display the source code file at `gno.land/r/<address>/run`

After running the message, this will cause an internal error due to the package not being found:

gnokey query vm/qfile --data "gno.land/r/g1jg8mtutu9khhfwc4nxmuhcpftf0pajdhfvsqf5/run". 

This behaves like hidden contract code and disappears after the message is run.

they are hidden in the current state but are available in the history (blocks), and should be indexed by indexers.
