/**
 * @file banner.ts
 * @description Console startup UI for the MCP server's non-stdio transports (HTTP and REPL):
 * the ASCII-art wordmark, a boxed server-info panel (version, transport, dashboard URL, port,
 * tool count, mutation/destructive policy state), a "ready" line, and a shutdown message. The
 * stdio transport never calls any of these, since stdout there is the MCP JSON-RPC channel.

 * MODULE_GUIDE — extended in-file reference (comments only; safe to read, never executed)
 * =============================================================================
 * **Purpose:** Dashboard module consumed by the React client, MCP tools, or desktop shell depending on deployment mode.
 *
 * ## Design constraints
 * - Local-first: no telemetry leaves the machine unless the user configures webhooks.
 * - Fail-safe hooks path on the server must never block Claude Code; UI mirrors that
 *   philosophy by degrading gracefully (empty states, stale badges, reconnect loops).
 * - Destructive flows stay behind explicit confirmation modals and server-side gates.
 * - Internationalization: user-visible strings belong in i18n JSON, not literals here.
 *
 * ## Remote data & SSH
 * Remote Data Sources let operators aggregate multiple machines. SSH entries describe
 * how to reach a peer dashboard; the global data scope (`dataScope.ts`) narrows every
 * scoped GET via `?sources=`. Health checks and import history surface in Settings.
 *
 * ## Public surface
 * - `printBanner` — exported API; see TSDoc on the symbol for behavior.
 * - `printServerInfo` — exported API; see TSDoc on the symbol for behavior.
 * - `printReady` — exported API; see TSDoc on the symbol for behavior.
 * - `printShutdown` — exported API; see TSDoc on the symbol for behavior.
 *
 * ## Testing pointers
 * - Prefer colocated `__tests__` with Vitest + Testing Library for UI.
 * - Server contract changes require `npm run test:server` and OpenAPI sync.
 * - MCP edits: `npm run mcp:typecheck` and `npm run mcp:build`.
 *
 * ## Related docs
 * - `ARCHITECTURE.md` — hooks → API → SQLite → WebSocket → UI pipeline.
 * - `docs/API.md` — REST reference.
 * - `.claude/skills/file-headers/` — mandatory `@author` header policy.
