Fix invalid dependency x402-fetch@^latest in @bankr/sdk

[ProtoJay4789]

Bug

@bankr/sdk has an invalid dependency tag: x402-fetch@^latest

The ^ prefix requires a valid semver version, not a dist-tag. This causes npm install to fail:

npm error code EINVALIDTAGNAME
npm error Invalid tag name "^latest" of package "x402-fetch@^latest"

Fix

Change x402-fetch@^latest to x402-fetch@^1.2.0 in package.json

Current version of x402-fetch is 1.2.0, so ^1.2.0 will get all compatible updates.

Impact

This blocks all developers from installing the SDK via npm. We are trying to integrate Bankr x402 Cloud with our 13 live APIs and cannot proceed until this is fixed.

Environment

• Node.js 20+
• npm 10+
• Platform: Linux (Ubuntu)

Workaround

For anyone blocked by this, you can install the dependencies separately:

npm install x402-fetch@1.2.0
npm install @bankr/sdk --legacy-peer-deps

Or in a single command:

npm install x402-fetch@1.2.0 @bankr/sdk --legacy-peer-deps

This gets you past the invalid tag while keeping the SDK functional.
