* Studio: start the Cloudflare tunnel for --secure even in --api-only, and add --api-only to `unsloth studio run`
--secure exposes ONLY the Cloudflare link (it forces a loopback bind), but
_cloudflare_tunnel_should_start gated the tunnel on `not api_only`, so
`run.py --secure --api-only` started no tunnel and then fail-closed with
"A secure Cloudflare link is not allowed". That blocked the natural headless
use: serve just the API (no web UI) over the authenticated tunnel.
Make --secure start the tunnel regardless of api_only (the non-secure path is
unchanged: tunnel only a 0.0.0.0 bind, never api-only Tauri or Colab). Then
expose --api-only on `unsloth studio run` and forward it through both the
re-exec args and the in-venv run_server call, so
`unsloth studio run --secure --api-only --model ...` is a one-liner secure API
server.
Verified end to end: `run.py --secure --api-only` now brings up the tunnel and
serves /api/health over it (200), with / returning 404 (no UI).
Tests: update the tunnel-gate truth table (secure+api-only now tunnels;
secure+colab still does not) and add --api-only registration + re-exec/in-venv
forwarding coverage to the run CLI tests.
* Trim comments to be succinct (no behavior change)
* studio: address review on parent --api-only and secure api-only CORS
- Reject --api-only on the parent `unsloth studio` group when a subcommand
is invoked, with the same redirect guidance used for --parallel/--secure;
otherwise the flag was silently dropped and the UI served anyway.
- Keep CORS any-origin for secure api-only serving: that mode publishes the
API over Cloudflare for remote browser clients, so the Tauri-only lockdown
(still applied to plain local api-only) would break preflight. Factored the
decision into cors_origins_for_mode() and gate it on api_only and not secure;
run_server exports UNSLOTH_SECURE before importing main.

* studio: suppress TAURI_PORT and de-dup test for headless run --api-only
- run_server gains emit_tauri_port (default True, unchanged for the Tauri/
desktop path). The new headless `run --api-only` path passes False so the
Tauri-only TAURI_PORT= line no longer prepends the documented URL/API key
banner (it ran even under --silent and could break one-liner parsers).
- Remove a duplicate test_reexec_forwards_api_only that shadowed the
parametrized one; fold the --secure --api-only case into it so the secure
headless path is actually collected.
