Two independent fixes:
- opencode-server.ts: stripDcpTags() removes <dcp-message-id>…</dcp-message-id>
tags from text deltas before they reach the frame/DB. Applied to all three
text paths (session.next.text.delta, message.part.delta text field,
handleUpdatedPart text type). Reasoning/tool paths untouched.
- useWorkspacePanes.ts: module-level closedPaneStack (capped at 10) captures
pane kind + chatIds on removePane and removeTab auto-remove. reopenPane()
pops the stack and re-attaches a new pane to the existing chat ids (chats
survive pane close server-side). hasClosedPanes drives conditional render.
- ChatTabBar.tsx: [+] is now instant new-tab (no dropdown); split-pane
dropdown (Columns2 icon) opens Chat/Term/Code in a new pane; reopen button
(RotateCcw icon) appears when closed panes exist.
- Workspace.tsx: pass reopenPane + hasClosedPanes through to ChatTabBar.
