Run logs defaulted to process.cwd()/data/run-logs, placing logs in
unexpected locations when launched from non-home directories. Now
defaults to ~/.paperclip/instances/<id>/data/run-logs/.
Fixes#89

The append method created a new WriteStream for every log chunk and resolved
the promise on the end callback (data flushed) rather than the close event
(fd released). Over many agent runs the leaked fds corrupted the fd table,
causing child_process.spawn to fail with EBADF.
Replace with fs.appendFile which properly opens, writes, and closes the fd
before resolving.
