fix: warn when localhost resolves to ::1 but Studio is bound only to 127.0.0.1 (#5994)
* fix: warn when localhost resolves to ::1 but Studio is bound only to 127.0.0.1

* studio: fix localhost/::1 warning suppression and cover _run wiring

Addresses the Codex review on #5994 plus review-team findings:

- Remove the `_local_port_open("::1", port)` early-return. Studio binds
  127.0.0.1 only, so a successful connect to ::1:<port> means a *different*
  process is there -- exactly when http://localhost opens the wrong service
  and the user most needs the warning. Dropping the probe also removes the
  ~0.25s startup latency and the probe/warn race.
- Extract the banner/warning block from `_run` into `_emit_startup_output`
  so the wiring is unit-testable, and make the mismatch vs wildcard paths
  an explicit if/elif (they are mutually exclusive by construction).
- Hoist the `_working_local_url` confirmation out of the try block and
  reorder `_stdout_color_ok` before its only caller.
- Tests: add `_emit_startup_output` integration coverage (banner
  include_stop_hint, warning emission, single stop hint), a regression test
  that ::1 being occupied does NOT suppress the warning, dual-stack and
  non-positive-port cases; drop the unreachable `None` getaddrinfo arm.
