merge: v0.4.0 performance & stability overhaul

Terminal:
- cache font variants + single reusable brush in render hot path;
  resolve cell colors once per cell; dispose GDI resources
- scrollback: List+RemoveRange -> O(1) ring buffer
- follow new output only when already at bottom (no more yank-to-bottom
  while reading history)
- alt-screen mouse wheel -> arrow keys (vim/htop scroll)
- answer DSR (ESC[5n/6n) and DA (ESC[c) queries so TUIs no longer hang
- remove dead code in OnKeyPress

Encoding correctness (garbled CJK across chunk boundaries):
- stateful UTF-8 Decoder in TTLInterpreter.OnData, SerialBridgeServer
  rx forwarding, and SessionLogger.Write

Sessions:
- ShellChannel: free proc-thread attribute list, close hProcess,
  notify '[ETTerms] shell process exited' in the tab
- SshChannel: surface ErrorOccurred / ShellStream.Closed in the tab;
  Write no longer throws into the UI thread on a dead connection

PDU:
- new shared ETTerms.PduCore project replaces the two drifted copies of
  PduController (GUI + PduMcp); logging via injected delegates
- batched SNMP GET (GetAllPortsStatus): 12-port poll is 3 UDP
  round-trips instead of 36 (StatusView polling + pdu_status tool)

Scripting:
- cap TTL receive buffer at 1MB; skip re-scan in wait when buffer
  length unchanged
- merge ScriptRunner.RunAsync/RunGroupAsync; new TtlScript helper
  dedups script picking + group-command checks (3 copies -> 1)

Misc:
- ConnectionStore: parse LastUsedUtc with InvariantCulture/RoundtripKind
- version 0.4.0; About changelog; CLAUDE.md notes (intentional group
  barrier behavior, SSH.NET reflection resize caveat)

+
+**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。

 **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.

 ## 📜 Version History
 
-### v0.1.0 (in development)
+### v0.3.3
+
+- **Terminal input fix** — after the terminal had printed output (Serial or PowerShell), switching away and back (minimize, or click another app) could leave it unable to accept typing or **Enter**, forcing a session reopen; idle sessions were never affected
+- Cause: once output built up scrollback, the terminal's scrollbar could steal keyboard focus on window re-activation. The scrollbar is now mouse-only and never takes focus, so input keeps working no matter how much has printed
+
+### v0.3.2
+
+- **Status → PDU tab** — a dedicated `Status` rail view hosts the PDU panel: connect by IP, auto-poll all 12 outlets every 3 s (background thread, no manual Refresh), with live current / power readouts
+- **Manual outlet control buttons** — each row has a **Control** button that toggles that port on/off over SNMP; the label tracks state (ON → "Turn OFF", OFF → "Turn ON"), the SNMP set runs off the UI thread, and the grid refreshes after the command
+
+### v0.3.1
+
+- **Terminal usability fixes** — added a **dark vertical scrollbar** (drag or click-to-page through long output instead of long mouse-wheel scrolling)
+- **Multi-line paste** into Kiro CLI / PSReadLine now pastes as a single block (**bracketed paste**, DEC mode 2004) instead of submitting each line immediately
+- Right-click copy now **clears the highlight** so you know it worked
+
+### v0.3.0
+
+- **AI-driven PDU power control (MCP)** — new `ETTerms.PduMcp` server lets AI agents (Kiro CLI / Claude CLI) control an SNMP PDU directly: outlets on/off, status, and power-cycle a DUT during automated tests
+- PDU runs over SNMP (UDP, non-exclusive), so the AI talks to it directly — the ETTerms GUI does not need to be running
+- Tools: `pdu_connect` / `pdu_list` / `pdu_set_port` / `pdu_get_port` / `pdu_status` / `pdu_power_cycle` / `pdu_disconnect`
+- **Settings → AI MCP** now registers both `etterms-serial` and `etterms-pdu` with one click; publishing the GUI auto-bundles both MCP servers
+
+### v0.2.2
+
+- **Terminal stability** — the terminal no longer freezes after minimizing or switching tabs (most noticeable with full-screen TUIs like Kiro CLI in PowerShell); a degenerate 1×1 size is no longer sent to the pseudo-console
+- **Shift+Enter** inserts a newline in the shell, so you can type multi-line commands (plain Enter still submits)
+- **High-DPI fixes** — text and buttons no longer clipped at 125% / 150% scaling (PerMonitorV2); toolbar / settings / sidebar / About now scale adaptively
+
+### 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

+# v0.3.2 — Status page with PDU outlet control
+
+## ✨ New features
+
+**Status page — control PDU outlets with buttons**
+* New **Status** view (the **⚡** icon on the left, between Terminal and Settings) with a **PDU** tab —
+  connect to your PDU by IP and see every outlet at a glance: state, current (mA) and power (W).
+* Each outlet row now has its own **Control** button: the label tracks the live state
+  (**Turn ON** when off, **Turn OFF** when on), so a single click flips that port. The SNMP command
+  runs off the UI thread, the grid refreshes after the change, and it resets cleanly on disconnect.
+* Outlet status **auto-refreshes every 3 seconds** in the background — no more manual Refresh button.
+* The PDU panel moved out of **Settings** into its own Status tab (Settings now keeps just
+  **Terminal / AI MCP**), and the layout is ready for more Status tabs later.
+
+## 🐛 Bug fixes
+
+**Local Shell startup**
+* Fixed: the local Shell no longer fails to start when its saved working folder is gone
+  (e.g. an unplugged USB drive or a deleted folder), which previously caused
+  `CreateProcess failed: 267 (ERROR_DIRECTORY)`. It now falls back to your home folder,
+  matching Windows PowerShell behavior.

+# v0.3.3 — Terminal input no longer dies after activity
+
+## 🐛 Bug fixes
+
+**Terminal stops accepting input after you switch away and back**
+* Fixed: once the terminal had printed some output (on a **Serial** or **PowerShell** tab),
+  switching away and back — minimizing the window, or clicking another app — could leave the
+  terminal unable to accept any typing or **Enter**. Previously the only way out was to close
+  and reopen the session (re-open the COM port / start a fresh PowerShell).
+* While the session sat idle, this never happened — it only showed up after enough output had
+  scrolled by, which is exactly when it bit you mid-task.
+* Cause: after enough output built up scrollback, the terminal's scrollbar could grab the
+  keyboard focus when the window regained focus, and the scrollbar has no keyboard handling —
+  so your keystrokes went nowhere. The scrollbar is now mouse-only and never takes focus, so
+  the terminal keeps working no matter how much it has printed.

+# v0.4.0 — Performance & stability overhaul
+
+## ✨ New features
+
+**Terminal performance overhaul**
+* Heavy output (long boot logs, big file dumps) now renders much more smoothly — drawing was
+  reworked to stop re-creating fonts and brushes on every frame.
+* Scroll-back history storage was rebuilt so the terminal stays fast no matter how much output
+  has accumulated; previously it got slower and slower once the history buffer filled up.
+
+**Full-screen apps (vim / htop) behave like a real terminal**
+* The mouse wheel now scrolls inside full-screen tools like `vim` and `htop` instead of doing nothing.
+* Tools that ask the terminal "where is the cursor?" now get an answer — fixes full-screen apps
+  that could hang on startup or draw at the wrong position.
+
+**Connection status you can actually see**
+* When an SSH connection drops or hits an error, a message now appears right in the tab —
+  no more sessions that silently stop responding.
+* When the local shell exits (e.g. you type `exit`), the tab shows
+  `[ETTerms] shell process exited` instead of just going dead.
+
+**Faster PDU status (GUI and AI)**
+* Outlet polling now bundles all 12 ports into a few SNMP requests instead of 36 separate ones —
+  the Status page refreshes faster, and an unreachable PDU no longer stalls the poll for minutes.
+* The AI `pdu_status` tool gets the same speed-up.
+
+## 🐛 Bug fixes
+
+**Garbled Chinese / non-English text**
+* Fixed: multi-byte characters could occasionally turn into `�` garbage when text was split
+  across data chunks — this affected TTL script `wait` matching, what the AI reads over the
+  serial bridge, and saved session log files. All three now decode correctly.
+
+**Scrolling**
+* Fixed: while you were scrolled back reading history, any new output yanked the view down to
+  the bottom. The view now stays where you are and only follows when you're already at the bottom.
+
+**Resource & stability**
+* Fixed small memory and handle leaks when opening and closing many local shell tabs over a
+  long session.
+* Fixed: typing into an SSH session after the connection died could crash the window — it now
+  just prints a short "write failed" note in the tab.
