merge: AI MCP one-click setup (v0.2.1)

feat: AI MCP one-click setup in Settings (v0.2.1)
Add Settings -> AI MCP tab with McpRegistrar to one-click register/remove the Serial MCP server into Claude Code (~/.claude.json) and Kiro (~/.kiro/settings/mcp.json); read-modify-write preserves other servers, atomic write-back. Each card shows a CLI verify command. Add PublishSerialMcp MSBuild target so a single GUI publish auto-bundles ETTerms.SerialMcp into the \ETTerms.SerialMcp\ subfolder, aligning with McpRegistrar.ResolveServerExe(). Bump version to 0.2.1. Update ARCHITECTURE/CLAUDE/README/README.zh-TW and About changelog.

 ## Publish / 打包慣例
 > 每次發 Release 都依此規則產出，方便辨識版本與一併攜帶 MCP server。
 **輸出位置（固定）：** `src\ETTerms\Publish\ETTerms_v{Version}\`
 - `{Version}` 取自 `src\ETTerms\ETTerms.csproj` 的 `<Version>`（例：`0.2.0`）。
 - 資料夾命名：`ETTerms_v{Version}`（前綴 `v`，例：`ETTerms_v0.2.0`）。
 - `Publish/` 已 gitignore（`publish/`），**不入 git**。
 **內容結構：**
 ```
 ETTerms_v0.2.0\
 ├── ETTerms v0.2.0.exe        # 主程式 apphost，改名為「ETTerms v{Version}.exe」
 ├── ETTerms.dll + 各相依 dll  # SSH.NET / SQLite / SnmpSharpNet / System.IO.Ports …
 └── ETTerms.SerialMcp\        # Serial MCP server，獨立發佈到子資料夾（相依 dll 與 GUI 隔離）
    ├── ETTerms.SerialMcp.exe
    └── ETTerms.SerialMcp.dll + 相依
 ```
 **規則：**
 1. **GUI publish 會自動帶上 MCP**：`ETTerms.csproj` 有 `PublishSerialMcp` target（`AfterTargets="Publish"`），會把 `ETTerms.SerialMcp` 一併發佈到 `ETTerms_v{Version}\ETTerms.SerialMcp\` **子資料夾**（與 GUI 相依 dll 隔離）。因此**只要發佈 GUI 一個指令**即可，不必再單獨發 MCP。
   - 對齊 `McpRegistrar.ResolveServerExe()`：它解析的 `<ETTerms.exe>\ETTerms.SerialMcp\ETTerms.SerialMcp.exe` 因此**必定存在**，AI MCP 一鍵設定寫進去的路徑才不會落空。
 2. **主 exe 改名**：`dotnet publish` 產生的 `ETTerms.exe` 重新命名為 **`ETTerms v{Version}.exe`**。
   - 可安全改名：.NET apphost 內部記錄要載入的 `ETTerms.dll`，**不靠自身檔名**，改名後仍正常啟動。
 3. **框架相依**：`--self-contained false -r win-x64`（目標機需已裝 .NET 8 Desktop Runtime）。
 **PowerShell 範例：**
 ```powershell
 $ver    = ([regex]::Match((Get-Content src\ETTerms\ETTerms.csproj -Raw), '<Version>([^<]+)</Version>')).Groups[1].Value
 $root   = "src\ETTerms\Publish\ETTerms_v$ver"

 **Key design: the GUI owns the COM port; the MCP server never opens it.** A COM port can be opened by only one process at a time, so rather than the MCP server grabbing it, the GUI is the sole owner and runs a local **named pipe server** (`SerialBridgeServer`). The standalone `ETTerms.SerialMcp` (launched by Kiro/Claude CLI) is a thin client: every `write` / `read` is forwarded over the pipe to the GUI, which does the real port I/O.

 - **AI MCP one-click setup** — new **Settings → AI MCP** tab registers the Serial MCP server into Claude Code (`~/.claude.json`) or Kiro (`~/.kiro/settings/mcp.json`) with a single button; existing MCP servers are preserved, and each card shows the verify command
 - Publish now auto-bundles `ETTerms.SerialMcp` into the app folder, so the registered path always resolves
 ### v0.2.0
 - **Phase 9: Serial MCP server** (`ETTerms.SerialMcp`) — AI agents (Kiro CLI / Claude CLI) send/receive on the serial port while you watch it live in the GUI
 - GUI is the sole COM-port owner; the MCP server bridges over a local named pipe (`SerialBridgeServer`) and never opens the port itself
 - Tools: `serial_list` / `serial_attach` / `serial_write` / `serial_read` / `serial_detach`; AI's TX echoed into the terminal tagged `[AI]`
 - New app icon (window / taskbar / executable); version shown in the title bar
 ### v0.1.0
 - Phases 1–8 complete: window shell, connection sidebar, tiling workspace, Serial / SSH / local Shell (ConPTY) / SFTP
 - Owner-drawn VT100 terminal rendering
 - TTL scripting engine (ported from MyTeraTerm) + Group sync execution
 - PDU power control (SNMP)
 - Settings / About
 - Packaging TBD
