Add supermodeltools.com/trial CTA

[jonathanpopham]

Adds the new /trial signup page link to the README so readers have a one-click path to start a free trial and get an API key.

Part of a coordinated set of PRs across the supermodeltools org adding /trial to each product's main user-facing surface.

Verified: https://supermodeltools.com/trial returns 200 (Pro $19/mo, Growth $199/mo, 14-day trial via Stripe).

Draft for review.

Walkthrough

The README's API key instruction now directs users to start a free trial at supermodeltools.com/trial instead of the Supermodel Dashboard, and still instructs to include the API key in the X-Api-Key request header.

Changes

Cohort / File(s)	Summary
Documentation Update README.md	Replaced Supermodel Dashboard URL with supermodeltools.com/trial and rephrased the guidance into a bold promotional callout; retained instruction to send API key in X-Api-Key header.

Poem

📝 The dashboard fades, a trial link takes flight,
Head to supermodeltools and start with delight,
Keep X-Api-Key in the header, no fuss, no fray,
Quick setup, small tweak — now you're on your way! ✨

In `@README.md`:
- Line 17: Update remaining API-key instructions to match the new trial CTA: in
README.md and quickstart.mdx replace the Dashboard URL/text that points to the
Dashboard with the /trial path (https://supermodeltools.com/trial) or, if there
is a deliberate difference, add a short clarifying sentence stating when to use
the Dashboard versus the /trial signup. Ensure the copy that tells users to send
the key in the X-Api-Key header remains unchanged and consistent across both
README.md and quickstart.mdx.
