chore: use caret version for the viem dependencies

Description

Here’s the PR description in plain Markdown, ready to copy:

PR: Switch viem (and related deps) to peerDependencies

Why

We previously declared viem (and in some cases wagmi) as a regular dependency in @reown/appkit, @reown/appkit-adapter-wagmi, and other internal packages.

This caused multiple versions of viem to be installed in consuming apps whenever users had their own viem in package.json.

Example problem case

User installs:

  pnpm add wagmi wagmi/connectors [email protected]

Our packages declare:

"dependencies": { "viem": "^0.3.0" }

Result: node_modules ends up with two different versions of viem (user’s 0.2.0 and our 0.3.x).
This breaks consumers because viem types and runtime are not compatible across multiple copies.

How

We now declare viem (and wagmi where imported directly) as peer dependencies:

"peerDependencies": {
  "viem": ">=xyz",
  "wagmi": ">=abc"
}

• peerDependencies: tell the app to provide these packages.
• Removed dependencies entries for viem and wagmi.

Benefits

• Single version of viem: Consumers control which version is installed, ensuring all packages share the same copy.
• Compatibility: Consumers can align wagmi + viem versions without fighting our pinned deps.
• Less duplication: Smaller node_modules, less chance of type mismatches.

Example dependency tree

Before

app
 ├─ wagmi
 ├─ [email protected]
 ├─ @reown/appkit
 │   └─ [email protected]   <-- duplicate
 └─ @reown/appkit-adapter-wagmi
     └─ [email protected]   <-- duplicate

After

app
 ├─ wagmi
 ├─ [email protected]   <-- single copy, shared
 ├─ @reown/appkit (peer -> uses app’s viem)
 └─ @reown/appkit-adapter-wagmi (peer -> uses app’s viem)
