* Tidy verbose Studio launch messages
The reachability failure hint, the loopback deploy block, and the stop
hint were several lines longer than they needed to be, and the banner
printed a Tip line that just repeated the URL already shown above. Shorten
them while keeping the useful detail (cloud provider names, the SSH
local-forward workaround, the relaunch command, the trusted-network and
macOS Ctrl+C notes). No behavior change, output wording only.
* Refine launch-message wording after review
Apply review feedback so the launch messages read well for both experts
and general users:
- reachability hint: restore the 'from your own computer' cue and put the
ssh command on its own line so it stops wrapping, name the cloud rules
precisely (GCP firewall / Azure NSG rule), and restore 'in your browser'
- loopback banner: add the missing colon, drop the Ctrl+C duplication
(the stop hint already covers it), and explain the exposure in plain
language instead of 'exposes the API on every interface'
- stop hint: trim so it fits an 80-column terminal without wrapping
- replace two pre-existing em dashes with --
