merge: keep terminal focus after activity (v0.3.3)

The terminal's DarkScrollBar derives from Control, which is selectable by
default. Once enough output accumulated to create scrollback, the scrollbar
became enabled and was the only selectable child of the TerminalView
(a ContainerControl). On window re-activation (minimize/restore, click away
and back) WinForms restored focus down the container chain onto the scrollbar,
which has no keyboard handling, so typing/Enter went nowhere until the session
was reopened. This affected both Serial and PowerShell tabs (shared TerminalView),
and only after output appeared — matching the reported symptom.

Make the scrollbar mouse-only: SetStyle(Selectable, false) + TabStop=false, so
it never takes keyboard focus and the TerminalView keeps focus itself, exactly
as it already did when idle (scrollbar disabled).

Bump version to 0.3.3 and add the About changelog entry.

 ## 📜 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
