chgserver: restore pager fds attached within runcommand session While rewriting chg in Rust, I noticed the server leaks the client's pager fd. This isn't a problem right now since the IPC process terminates earlier than the pager, but I believe the fds attached within a "runcommand" request should be released as soon as the session ends.
