Loki Mode v7.72.0

Public preview link: share the app Loki built

loki preview --public creates a PUBLIC URL for the app Loki built and is
running locally, by wrapping YOUR OWN tunnel client (cloudflared or ngrok), so
you can send a teammate or client a link to the live build. Loki never proxies
the traffic and never bundles or downloads a tunnel binary -- your tunnel
account is what egresses, by your explicit choice, preserving the
"your keys, nothing leaves your network" model.

loki preview --public                 # auto-detect cloudflared, then ngrok
loki preview --public --provider ngrok
loki preview --public --yes           # skip the consent prompt (warning still shown)

• Consent-gated, default-OFF: it always prints a clear warning (the app may have
  no auth; anyone with the URL can reach it; it stays up until you stop it), and
  on an interactive terminal asks [y/N] (default no). Non-interactive use
  requires --yes; without it on a non-TTY, it refuses rather than silently
  exposing anything.
• Preconditions: the app must be running (state.json present, status running) and
  its local port must actually respond -- a dead port is never tunneled.
• Provider allowlist (cloudflared|ngrok only), honest install hint when neither
  is present (never a fake success), and a foreground lifecycle with Ctrl+C +
  trap teardown so a failed or finished attempt never leaves an orphaned public
  tunnel. Host-header rewrite is on by default (fixes the common dev-server
  "Invalid Host header"); disable with --no-host-rewrite.
• Architect-planned (docs/PREVIEW-LINK-PLAN.md), reviewed by a 3-reviewer council
  to unanimous approve (consent-unbypassable, no-orphan-tunnel, and no-injection
  all independently verified). bash-only; no dist behavior change.
