Originally used ps-tree which relied on `ps` on *nix. But if the system
didn't have `ps` at all, we'd try to kill the child process, but alas
this would not always work, as we're spawning `sh` and _then_ node, so
the kill would only kill the `sh` process, and not the running node
process.
The new @remy/pstree lib sniffs for `ps` and defers to ps-tree,
otherwise it will walk /proc and map the PPID to the child process
allowing nodemon to fully clean up.
* fix: pass through execArgs from config
Also updating some deps and linting tweaks
* chore: add message on postinstall
Lost funds from gratipay and codesponsor 😢
