Add Provenance MCP server to .mcp.json.example and INSTALL.md

[crtahlin]

Request

Add the Swarm Provenance MCP server to .mcp.json.example and INSTALL.md so Datacore users can discover and install it.

Context

The Provenance MCP server (datafund/swarm_provenance_MCP) provides AI agents with tools for:

• Swarm postage stamp management (purchase, extend, list)
• Data upload/download to Swarm decentralized storage
• Provenance metadata storage (immutable, verifiable records)
• On-chain hash anchoring and verification (Base Sepolia)
• Transformation lineage tracking

It has a Docker zero-install option which makes it easy to add.

Suggested changes

.mcp.json.example

Add after the datacore entry (see #14):

"swarm-provenance": {
  "command": "docker",
  "args": [
    "run", "-i", "--rm",
    "-e", "SWARM_GATEWAY_URL=https://provenance-gateway.datafund.io",
    "ghcr.io/datafund/swarm-provenance-mcp"
  ],
  "comment": "Swarm Provenance MCP — stamp management, data storage, on-chain anchoring. Requires Docker."
}

For on-chain features, users add -e CHAIN_ENABLED=true -e PROVENANCE_WALLET_KEY=0x... to args.
