/**
 * Seed the MCP service account at startup.
 *
 * Creates a single `mcp-service` bot account with two API keys:
 *   - `mcp:read`  — read-safe tools only (discovery, monitoring)
 *   - `mcp:full`  — all tools (automation, orchestration)
 *
 * Idempotent — skips creation if the account already exists.
 * Keys are generated once and logged; they cannot be retrieved again.
