Altimate Setup

Guide the user through configuring their Altimate platform credentials.

Steps

Check existing config: Read ~/.altimate/altimate.json. If it exists and is valid, show the current config (mask the API key) and ask if they want to update it.
Gather credentials: Ask the user for:
- Altimate URL (default: https://api.myaltimate.com)
- Instance name (their tenant/org name, e.g. megatenant)
- API key (from Altimate platform settings)
- MCP server URL (optional, default: https://mcpserver.getaltimate.com/sse)
Write config: Create ~/.altimate/ directory if needed, then write ~/.altimate/altimate.json:
```
{
  "altimateUrl": "<url>",
  "altimateInstanceName": "<instance>",
  "altimateApiKey": "<key>",
  "mcpServerUrl": "<mcp-url>"
}
```
Then set permissions to owner-only: chmod 600 ~/.altimate/altimate.json
Validate: Call the datamate_manager tool with operation: "list" to verify the credentials work. Report success or failure to the user.
