Adds a Shop Pay wallet page and links it from the payments docs.

Changes

• New integrations/wallets/shop-pay.mdx: connect through KERNEL's Shop app, choose a saved card, create and authorize a card at checkout, fill, report the outcome with confirm_transaction, and the item reference. Live only, USD only.
• Wallet overview: Shop Pay row, the shop_pay_oauth action, and that Shop Pay has no provider configuration.
• Payments overview: Shop Pay in the how-it-works steps, including reporting the outcome with confirm_transaction. Nav entry after Link.
• Browser agent walkthrough: points to the Shop Pay page, recommends a headful or 2GiB+ headless browser for checkout, and notes Stripe's "save my information with Link" box, which blocks payment without a phone number.

Before merging

• The CLI tabs need a CLI release that includes CLI: Update Go SDK to 738369d524a3806832577f6793dde7eaf15c5725 cli#304.

Testing

• Ran the TypeScript and Python examples against the prod API with SDK 0.139.0: payment methods, create, update before authorize, authorize at checkout and for merchant_url, re-reading for a fresh approval link, and the 409s for confirming while pending and updating after authorize. Each card was deleted before approval.
• Fill and confirm_transaction ran in two real $1 purchases through the MCP and CLI the same day.
• All TypeScript blocks typecheck together against the SDK; mint validate and mint broken-links pass.

Documentation-only changes with no runtime or API behavior modifications in this repo.

Overview
Adds Shop Pay as a documented wallet provider alongside Link and Agentcard, with a new integrations/wallets/shop-pay.mdx guide covering OAuth via KERNEL's Shop app, optional saved-card selection, checkout authorize, fill, and post-checkout confirm_transaction (live, USD only).

The payments overview, wallet overview, and docs.json nav are updated to include Shop Pay, document shop_pay_oauth, note there is no BYO provider config, and tie Shop Pay into the shared payment lifecycle. The browser agent payments walkthrough now points readers to the Shop Pay guide, adds a 2GiB+ headless browser tip for heavy checkouts, and documents unchecking Stripe's pre-checked "save with Link" option when it would block submission without a phone number.
