merge: PDU MCP server (v0.3.0)

feat(pdu): add PDU MCP server for AI-driven SNMP power control
New ETTerms.PduMcp stdio MCP server lets AI agents (Kiro/Claude CLI) control SNMP PDU outlets directly. Unlike serial, SNMP is non-exclusive so it talks to the PDU directly without bridging through the GUI. Tools: pdu_connect / pdu_list / pdu_set_port / pdu_get_port / pdu_status / pdu_power_cycle / pdu_disconnect. - McpRegistrar now registers both etterms-serial and etterms-pdu in one click - Settings -> AI MCP shows both server paths - publish target (PublishMcpServers) bundles both MCP servers - bump version to 0.3.0, update About changelog, ARCHITECTURE.md, CLAUDE.md

 ETTerms 提供**兩個獨立的 stdio MCP server**給 AI agent（Kiro CLI / Claude CLI）：
 - **`ETTerms.SerialMcp`** — 收發 serial。COM port 獨佔，故由 GUI 唯一持有、MCP 經本機 named pipe 橋接（見下方）。
 - **`ETTerms.PduMcp`** — 控制 SNMP PDU 電源插座。SNMP(UDP) 非獨佔，故 MCP **直接打 SNMP**，不需 GUI 在跑、也不經 pipe。
 兩者都能用 GUI **Settings → AI MCP** 一鍵 Setup（`McpRegistrar` 會同時註冊 `etterms-serial` 與 `etterms-pdu`）。

 ### PDU MCP Server（v0.3.0）
 > 讓 AI agent 直接控制 SNMP PDU 的電源插座，**典型用途：測試中自動 power-cycle DUT**。
 **關鍵設計：直接打 SNMP，不經 GUI 橋接。** 與 serial 不同，PDU 走 SNMP（UDP）**非獨佔**——多個行程可同時對同一台 PDU 下命令。因此 `ETTerms.PduMcp` 不需要像 serial 那樣繞 GUI 的 named pipe，而是內含一份精簡版 `PduController`（OID 邏輯複製自 GUI 的 `Scripting/Pdu/PduController`，診斷改走 stderr 以免污染 stdio JSON-RPC）直接與 PDU 對話。**好處：GUI 不必開著，AI 也能控制 PDU；最少程式碼、最穩。**

 **暴露的工具：**

 | `pdu_connect` | ip | 以 SNMP 連線並驗證 PDU 回應，成功回傳 model name；控制前必須先呼叫 |
 | `pdu_list` | — | 列出本 session 已連線的 PDU（依 IP） |
 | `pdu_set_port` | ip, port, on | 將某插座開(on=true)/關(off=false) |
 | `pdu_get_port` | ip, port | 讀單一插座的狀態 / 電流(mA) / 功率(W) |
 | `pdu_status` | ip | 讀全部 12 個插座的狀態 / 電流 / 功率 |
 | `pdu_power_cycle` | ip, port, offSeconds? | 關 → 等 offSeconds → 開（重啟 DUT） |

 **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_v0.3.0\
 ├── ETTerms v0.3.0.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 …

 ```
 **規則：**
 1. **GUI publish 會自動帶上兩個 MCP server**：`ETTerms.csproj` 有 `PublishMcpServers` target（`AfterTargets="Publish"`），會把 `ETTerms.SerialMcp` 與 `ETTerms.PduMcp` 一併發佈到各自的 `<publish>\<server>\` **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>\<server>\<server>.exe` 因此**必定存在**，AI MCP 一鍵設定寫進去的路徑才不會落空。
   - MCP 子發佈會**跟隨 GUI 的 `SelfContained` 設定**（target 內以 `$(SelfContained)` 傳入）：框架相依版的 MCP 也框架相依；portable 版的 MCP 也免 runtime。
 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。
 ### 兩種發佈版本（兩個都要產出）
 | 版本 | 資料夾 | 指令旗標 | 需 .NET Runtime？ | 用途 |
 |------|--------|----------|-------------------|------|
 | **A. 框架相依（預設）** | `ETTerms_v{Version}\` | `--self-contained false` | ✅ 需先裝 .NET 8 Desktop Runtime | 體積小；給已具備 runtime 的環境 |
 | **B. Portable（免安裝）** | `ETTerms_v{Version}_portable\` | `--self-contained true` | ❌ 不需要，runtime 已內含 | 體積大（約 240MB）；給受 MIS 管控、不便裝 runtime 的環境，解壓即用、免系統管理員權限 |
 > ⚠️ **不要開 trimming**（`PublishTrimmed`）：WinForms 大量用反射，trim 後易在執行時出錯。
 **PowerShell 範例（一次產出兩種）：**
 ```powershell
 $ver = ([regex]::Match((Get-Content src\ETTerms\ETTerms.csproj -Raw), '<Version>([^<]+)</Version>')).Groups[1].Value
 # A. 框架相依版 → ETTerms_v{Version}\

-### v0.1.0 (in development)
+### v0.2.1
 - **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
 **Planned**
 - Phase 9: Serial MCP server (`ETTerms.SerialMcp`) — let AI agents (Kiro CLI / Claude CLI) drive the serial port directly

etwen	6a85a48e6d	merge: PDU MCP server (v0.3.0)	2026-06-08 10:12:24 +08:00
etwen	02f4ac49e8	feat(pdu): add PDU MCP server for AI-driven SNMP power control New ETTerms.PduMcp stdio MCP server lets AI agents (Kiro/Claude CLI) control SNMP PDU outlets directly. Unlike serial, SNMP is non-exclusive so it talks to the PDU directly without bridging through the GUI. Tools: pdu_connect / pdu_list / pdu_set_port / pdu_get_port / pdu_status / pdu_power_cycle / pdu_disconnect. - McpRegistrar now registers both etterms-serial and etterms-pdu in one click - Settings -> AI MCP shows both server paths - publish target (PublishMcpServers) bundles both MCP servers - bump version to 0.3.0, update About changelog, ARCHITECTURE.md, CLAUDE.md	2026-06-08 10:12:15 +08:00

etwen	776509cc6c	merge: high-DPI scaling & layout fixes (v0.2.2)	2026-06-05 13:33:33 +08:00
etwen	a66d2a19e4	fix(ui): high-DPI scaling and layout clipping (v0.2.2) Switch to AutoScaleMode.Dpi (PerMonitorV2) so control sizes scale by the exact DPI ratio, matching point-font rendering and eliminating text/button clipping at 125%/150%. Make toolbar, settings, sidebar buttons and About labels AutoSize; align left tab bar with workspace toolbar (both 40px); About cards now auto-grow and the left column scrolls. ActivityRail cell size is DPI-aware. No version bump.	2026-06-05 13:33:25 +08:00
etwen	68b727f38a	merge: terminal resize/Shift+Enter bugfixes (v0.2.2)	2026-06-05 11:02:45 +08:00
etwen	e5c10afd94	fix(terminal): stop minimize/switch from freezing ConPTY; add Shift+Enter newline (v0.2.2) OnSizeChanged now ignores degenerate sizes (minimized / smaller than one cell), so ConPTY no longer receives a 1x1 size that collapsed full-screen TUIs like Kiro CLI. ScreenBuffer.Resize reflows both the live and saved alt-screen buffers instead of discarding the main-screen backup. TerminalInput.Map sends LF for Shift+Enter (CR for plain Enter) so the shell inserts a newline for multi-line input. Bump version to 0.2.2 and add About changelog entry.	2026-06-05 11:02:39 +08:00
etwen	fc97e04846	build: add self-contained portable publish variant (v0.2.1) PublishSerialMcp target now inherits the GUI's SelfContained setting, so a --self-contained true publish also produces a runtime-free ETTerms.SerialMcp. Document both publish variants in ARCHITECTURE.md / CLAUDE.md: framework-dependent ETTerms_v{Version}\ and portable ETTerms_v{Version}_portable\ (no .NET runtime install needed).	2026-06-05 09:33:24 +08:00
etwen	2ac260489f	merge: AI MCP one-click setup (v0.2.1)	2026-06-05 08:58:20 +08:00
etwen	7ba3fadb87	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.	2026-06-05 08:58:02 +08:00
etwenandClaude Opus 4.8	10ec900386	docs: add v0.2.0 changelog & publish convention; drop "Version" label from title - About: add v0.2.0 "Beta Version Release" changelog entry. - MainForm: title bar now shows "ETTerms vX.Y.Z" (drop the word "Version"). - ARCHITECTURE.md + CLAUDE.md: document the publish convention -- output to src\ETTerms\Publish\ETTerms_v{Version}\, main exe renamed to "ETTerms v{Version}.exe", ETTerms.SerialMcp published into a subfolder.
