`pnpm dev --tunnel` published a bare URL under a "public, unauthenticated"
header. That label was wrong for the flag's own default target: --tunnel with
no port aims at the dashboard, which is bearer-token gated, so the recipient
of a shared link got a 401 with no token to supply.
resolveDevTunnelAuth() now classifies the target and the banner says what is
actually true of it:
token dashboard with auth on — prints the token and a ?token= link,
resolved from FUSION_DASHBOARD_TOKEN, FUSION_DAEMON_TOKEN,
then ~/.fusion/settings.json
token-pending first run, token not minted yet — defers to the dashboard's
own startup banner
no-auth --no-auth is on; the dashboard really is open
foreign a non-dashboard port; Fusion has no auth to lend it, the only
genuinely ungated case
Auth resolves at banner time rather than flag-parse time so a token the dev
child mints on a first authenticated run is already readable.
