fix(shell-init): suppress cd output

Browse source 
If `cd` causes output on stdout (e.g., via the use of noisy `chpwd` hooks on
zsh), then the resultant `PATH` exported to the shell will be polluted with that
output, and `safe-chain` will not function.  To prevent this, this PR updates
`init-posix.sh` and `unix-wrapper.template.sh` to suppress any output on stdout
during `cd`.
