docs: add Hive crypto MCP server list

[rishabhng]

Description

Adds Hive Intelligence's maintained Awesome Crypto MCP Servers list to ADDITIONAL.md next to the existing MCP resource lists.

Server Details

• Server: N/A
• Changes to: Additional community resources

Motivation and Context

The resources section already links general MCP server lists and one crypto-specific list. This adds another maintained crypto/Web3 MCP resource covering DeFi, wallets, trading, on-chain data, and blockchain MCP servers.

How Has This Been Tested?

• git diff --check
• npx --yes markdown-link-check ADDITIONAL.md confirms the new Hive links pass; the command currently fails on pre-existing unrelated third-party links in ADDITIONAL.md.

Breaking Changes

None.

Types of changes

• Documentation update

Checklist

• I have read the MCP Protocol Documentation
• My code follows the repository's style guidelines
• New and existing tests pass locally where applicable

Maintainer note: this is a docs-only addition to ADDITIONAL.md, not a package/server change. All reported Python and TypeScript checks are green, and the target repo is a curated crypto MCP list maintained under hive-intel/awesome-crypto-mcp-servers with risk-routing notes for wallet, trading, and payment MCPs. Happy to adjust wording if you prefer a more neutral description.
