merge: Status page with PDU outlet control buttons (v0.3.2)

- New left-rail Status view (StatusView.cs) hosting the PDU tab; PDU panel moved out of SettingsView and auto-polls all 12 outlets every 3s on a background thread (no manual Refresh).

- Each outlet row gets a Control button (DataGridViewButtonColumn) that toggles the port via SNMP off the UI thread, re-reads after ~400ms, and resets the grid on disconnect.

- fix(shell): ShellChannel falls back to the user home folder when StartupDirectory no longer exists (avoids CreateProcess 267).

- docs: update ARCHITECTURE / CLAUDE / README / README.zh-TW and About changelog; bump version to 0.3.2.

 ## 📜 Version History
 
+### 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
