SDK: New Docs

[chakra-guy]

Description

This PR restructures the MetaMask documentation to clearly separate the Wallet API from the SDK. Historically, both lived under a single “Wallet” section because they addressed similar needs (interacting with the MetaMask wallet). However, the SDK’s future scope now extends well beyond wallet connectivity—it’s evolving into a broader toolkit for building on-chain applications, connecting to multiple wallets, and integrating other Web3 services (e.g., on-ramps, swaps, smart accounts, and embedded wallets).

By splitting the Wallet API and the SDK into distinct sections, we create a more intuitive navigation and mental model for developers. Going forward, the Wallet API remains focused solely on the MetaMask Wallet itself, while the SDK becomes a fully versioned, standalone developer toolkit encompassing multiple modules.

Key changes:

• Top-level Restructure: Introduces separate top-level sections for the Wallet API and the SDK instead of a single “Wallet” section.
• Homepage Update: The documentation homepage now routes developers directly to the product area they need (e.g., Snaps, Wallet API, SDK), making it easier to identify the relevant path from the start.
• Wallet API Section: Retains and refines existing Wallet API content, removing or redirecting any SDK-related references.
• SDK Section: Establishes a new SDK structure, pulled from and expanded beyond the original Wallet docs. This includes organizing content around the broader on-chain application development toolkit vision.
• Versioning Ready: Splitting the two makes it straightforward to introduce versioning to the SDK without confusing Wallet API users or mixing product lifecycles.
• Vercel Redirects: Vercel redirect links have been updated to account for the split.
